well I had like 3 different versions of Starforce

. Removed them all.
I downloaded and installed the nforce stuff. Still no luck
I can't use winflash. It wants a sys file, I assume IO.sys, and as I said as far as I know I don't have it. Is there another sys file I have to use?
I am grasping at straws here, and I apologise for not having any luck. I am mentioning things in case they matter.
my computer's HD is split into a C drive and a D:backup drive. There are is also a floppy drive (A) and the CD drive (E). IS it getting blocked by all the drives ie. no letters left or something. When I use the DVD playing software that came it seems to try to use my CD drive (E). I tried disabling the E drive but it made no difference.
