Thanks for your response. I too was discouraged that someone had a similar
problem, resolved it, and didn't come back to say how.

Anyway, I did try your suggestion and followed the instructions in the link.
I inserted the Windows XP CD, pressed enter when asked if I wanted to start
using CD, and waited to be prompted to press R for repair. Then got the
command prompt. When entering cd system32, the response back was: The path
or file specified is not valid; when entering ren kernel32.dll kernel32.old,
the response was: The rename operation failed; when entering expand
d:\i386\kernel32.dl_, the response was: Unable to create file Kernel 32.dll 0
file(s) expanded. So I typed in exit, and the loop began again. No change.

Any ideas about the messages I received? Should I have done something
differently? Anything else I can try?

Thanks,
Maria
