I've got an error after launching..

lnFiDeL

Hello,

I've got kinda gay problem cuz when I launch the game it immediately crashes my PC and makes it restarting. It happens everytime I start the game... I had this problem few months ago and I took working version from my friend and it was working, however when you made another patch it happened again...
So my question is: What's going on and how can I fix it w/o copying all the time the client from my friend?

Thanks for help.
