error vendor license

[JimM88]

upgrading to NJ8 I have been moving add-ons / upgrades etc. this one vendor at one time I must have used the 7 day trial and that message comes up says put in license key. I do that and it does not recognize the key. they sent me another and that has same result / I sent them a log file never heard back, I removed all old files from vendor and downloaded again same results. ( I did put NJ8 on a clean machine and tried it there, and it worked but never asked for license key so I'm assuming it is another trial version)

this is the error message :

We'll need to hear what the developer reports prior to doing any NinjaTrader troubleshooting as the developer would be more familiar with license-related errors than we would.

Is the other PC which works without issue using the same source of internet as the PC that you're getting this error on? Are they both hardwired/wireless?

Who is the developer? Can you contact us via email so we may try to get a response from the vendor collectively? Please send me your log and trace files so that I may look into what occurred.

You can do this by going to the Control Center-> Help-> Email Support

Ensuring 'Log and Trace Files' is checked will include these files. This is checked by default.

Please reference the following ticket number in the body of the email: 2050349 ATTN Patrick G. Also, include a link to this forum post and the vendor's name/email address.
