c# - System.BadImageFormatException - Invalid Token when updating DLL to newest version? -

I have some projects going, which are being used by some company-specific DLLs. I am just downloading and updating to the latest version and now I am getting this error. I do not believe this is unique to DLL itself, new projects are not expected in my project. Stack trace is not very useful.

Server error in the '/ dashbad' application.

Invalid token.
