Unable to retrieve type info loading Ninja Addonbase- Urgent

[Graci117]

I am getting this error when I start Ninjatrader. It is for a few Nito assemblies Unable to retrieve type info error when loading Ninja addonbase form assembly Nito.Cancellation, Nito.Disposables, etc...There are like 4 or 5 errors. I am not sure which indicator uses that assembly and how to get rid of the error. I looked at this thread but the video link is broken

I cannot right now uninstall NT8 and reinstall because I have some indicators that are machine specific and I will not be able to reinstall them. I have a backup and tried to restore but that didn't help.

Please help as soon as possible.

NVM...I figured it out. It was to do with the Apex copier. I removed Copier from the NT8 using Apex toolkit and installed again and it started working.
