Microsoft Visual C++: MSDEV.EXE

Hello,
I think I am having a problem with Visual Studio C++ 6.0. The problem began after I did a forced termination of the Visual Studio C++ 6.0 after it freezed. Now every time I try to open or to add a file, an error massage appear saying that the program faced a problem and it will terminate. Giving three options weather to (or not to) send a report, or to debug. So if I choose the first two options, another error massage appears titled "Microsoft Visual C++: MSDEV.EXE - Application Error" and saying that "the instruction at 0x73d211a3 referenced memory at 0x00000004. the memory could not be read" and the VS shuts down. However, if I choose to debug, I get the following error "Unhandled exception in MSDEV.EXE(DEVSHL.DLL): 0xC0000005: Access Violation".
I am using Windows XP SP.3 and note that the VS was working properly before I did the 5th "end task".

Any ideas ?

Thanks
