ET probs again

Okay now i have a serious problem.So i finally found out (with ant1y wich crashed py pc) that i had to buy new vid_card. After we've tried many ways to install ATI Catalyst my ET wont work so i had to restart my system wich didn't work either. Now i can't play ET (if i could will be with this shit graphics) and i have to re-dl many things since i restarded my system. So i need help!!!

This is the msg i get (won't even load ET so it's not r_mode bug i guess)

ET 2.60b win-x86 May 8 2006
