[urgent] Ninja startup issue, windows event viewer, application error

[PolarBear]

Hi,
Ninja 8 was working fine on my PC. Earlier today I was downloading some ES replay data (which I've done many times before). Closed Ninja down. Rebooted and went to restart ninja and nothing happened. No splash screen. No log files or trace files created (the last ones were from when I closed down the app earlier). Tried opening several times.

last log (unrelated I believe):
2022-02-28 00:01:30:600|3|2|Connection lost to the NinjaTrader Information Server: is-us-nt-001.ninjatrader.com

I subseqently went into Win10 Event Viewer -> administrative events; and found the following 2 errors (repeateable, each time I try to launch Ninja):
1) Application: NinjaTrader.exe

I note that I diabled a few 3rd party startup apps between when the problem started ocuring. One was the oneDrive app, which is the only one that I thought may have a connection, as that syncs the Documents folder (which Ninja saves the user info in).
I've subsequently enabled that, rebooted, but still the same issue as above.

All the files are where they should be (ie: nothing was deleted when I disabled the oneDrive syncing above).

I've also tried to enter the Ninja safe mode by holding down control key on launch. This doesn't help, still same 2 errors above.

Can you advise what directory this is likely looking for and flagging the error? It's something immediately on startup as the splash screen isn't even coming up. Please let me know instructions how to reset or something.
I have a lot of data and strategies so I don't want to mess with anything I have set up.

Urgent as I'm logging data and feeding this into my active trading.
thanks,
Daniel

I realized that one cause of the issue could have been that my internet connection was playing up, so I was actually trying to download replay data for the ES as my internet connection went down. That never finished and I closed Ninja to restart my PC and sort my internet connection.

Ok I figureed out how to fix. I'd still like NT staff to comment on what caused this, but it appears, some issue with paths.
I found this thread: https://ninjatrader.com/support/foru...ath#post521946

I created a new shortcut to NT8 and specified the direct path to my files as below.
This appears to have solved the issue.

Target: "C:\Program Files (x86)\NinjaTrader 8\bin64\NinjaTrader.exe" /d "C:\trading\2021\_NT8 Folder 2021"
Start in: "C:\Program Files (x86)\NinjaTrader 8\bin64"

Hello Polar Bear,

Thanks for the post.

An issue with file paths can certainly lead to the behavior you described above, particularly based on the " System.IO.DirectoryNotFoundException" error you received. NinjaTrader is programmed to look for installation (C:\Program Files (x86)) and user files (Documents\NinjaTrader 8) in two very specific paths. If you move those files/folders without re-mapping your documents appropriately and reinstalling the platform, it won't have any way to access its own folders which it needs to run.

Please feel free to reach out with any further NinjaTrader inquiry you may have,
