Problem importing Ninjascript add ons

[manraygun]

Hi, I just updated to version 8.0.28.0 64-bit and the platform give me this error message, then crashes when I try to import a Ninjascript add on. Everything else seems to work fine.
Thanks.

You would need more information that this - what add-on are you trying to import? Does it give any details in the log or trace files? Have you emailed the log and trace files to support?

[manraygun]

Crashes before I can upload any indicator.

I deleted this indicator but continue to get the error message.

Looks like this is the problem actually.

What version did you update from? If it's prior to 8.0.27, could be some incompatible indicators because that version change the ninja internal sql database

Hello manraygun,

The error mentions an AccessViolation with the database. This could also be a database corruption or something external to NinjaTrader is accessing the database file. Please make sure you do not have any sync or file scanning software running on the documents directory while the platform is running. If you do close those apps and restart NinjaTrader if you did have anything running, does that correct the error?

You can also try recreating the db by doing the following:

1. With NinjaTrader closed open the folder Documents\NinjaTrader 8\db
2. Rename NinjaTrader.sqlite to NinjaTrader.Old.sqlite
3. Then start the platform

Thanks, Jesse. I tried your suggestions with no luck. I wound up installing Version 8.0.28.0 despite hearing some negatives about it. The good news is the platform no longer crashes but I still get the error message below when trying to import an add on. Also, now some of my indicators are missing. How can I get the old indicator errors fixed and bring new ones in?

[manraygun]

These are the new errors. I would think I could re-import the two problem indicators but I have to resolve the errors before I can import anything. Confused.

Hello manraygun,

The error you are seeing is because NinjaScript is not compiled, you need to use the NinjaScript editor to compile and check for errors. The other errors in the log are because NinjScript is not compiled, the custom items are removed when NinjaScript is not compiled.

[manraygun]

Every indicator when compiled, including all the native ones, gives the same CS0006 error message. What do you think?
Thanks.

It certainly looks like you have some files in Documents -> NinjaTrader 8 -> bin -> Custom that maybe don't belong there. In the screenshot all we can see are PJSF and Book but neither of those come with NinjaTrader. If they're part of a third-party add-on they may not be installed correctly. I would suggest to get rid of those, and then do a repair installation.

[NinjaTrader_Jesse]

Hello manraygun,

Those seem to be referenced dlls that are missing. If you removed those items but still have the reference that would cause that error. Please check the path listed for each item in the picture and see if the file exists. If the file does not exist use the NinjaScript editor to Right click -> References and then remove those items from the list.

[manraygun]

What a disaster. I got rid of the dlls reference issue and now I'm back to the original error message from my first post.
I've restored my computer to where it was before I upgraded and now would like to install version 8.0.27.1 which is the last version that an important indicator I use can run with.
Can you tell me where to download 8.0.27.1? I don't see it available on the download page.
Thanks.

[QuantKey_Bruce]

You have the attempted to read/write protected memory error with no custom DLLs and no custom NinjaScript? That doesn't seem possible... have you tried removing all of the custom DLLs and custom NinjaScript to get the platform running in a stable situation before you put those back one at a time?

[manraygun]

Thanks for the suggestion.
How do I distinguish the custom DLLs and custom NinjaScripts from non-custom? Also, I have a couple of custom drawing tools.
I'll delete everything custom if I know which are which.
