No error but doesn't work - cache cleared

[Crossbowman]

I started creating a mod. I removed a lot of things in the XML files, I put what I needed and I cleared all the errors. Now there is no error message when loading XML files, but after, there is a message saying that the game must end (ask to send error report to microsoft). And I cleared my cache. Does anyone know what may be my problem? Maybe I say nothing, but that's almost all I can say...
