When I tried to open mantis today to run a tournament it would not open and just gave me an error of some file could not be accessed. I can't remember exactly which one. When I returned home to attempt to fix this by reinstalling Mantis and .NET (with and without the latest hotfix), I tried it both ways it starting giving off a new error now.
Microsoft .NET Framework
An unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will be shut down immediately.
Extrernal component has thrown an exception.
Continue / Quit
This is the error shown when attempting to start Mantis, I'm on Windows Xp.
Any help would be good.
