Technical problem

[Ratel]

Guys where do I go to to find out how to fix a technical problem?
It is now the 3rd time this year that I have to re-install my MBT or WW2 game.
What happens is that when I play a PBEM, I copy the turn sent to me by my opponent into the PBEM folder. Then, when I enter the game everything works fine until I click on the PBEM tab to view my PBEM battle list. As soon as I do that, my game crash to desktop. Nothing works to fix it except by re-installing the whole game.
Sometimes when I receive a turn from another player, the file name also seems to change name by itself.
Can anybody point me in the right direction please?
