[RESOLVED] Win98 Msdos prompt

Everytime I try to access the prompt, I get a gpf, which states, "winoldap has performed an illegal, etc. Something with the commctrl.dll, in registry. I will appreciate your help. Plus, it is doing something with my A drive. I know it works, because when i use my emergency disk it reads the a: drive, without a prob. But in win98, it acts as though it is going to read it, but just hangs. I Ctrl, alt, del and it will stop hanging but the light stays on and i can no longer access my computer.
