I have W2k and i upgraded detonators to 5.16 windows show me window with information, that there was error and windows could not find one or more files. After reboot i have vga mode ... when i change driver to 5.16 it is working perfecty until reboot. I tried with other versions, but same problem. I have removed all detonator files from win dir also. Stilll same problem - not all files copied, vga mode. Detonators are ok, on second machine no problems at all. Is there anybody who could help me ?????
