Hello,

I need help, I installed Windows 7 today and had to
unlock LFS again, so far so good work
and is working perfectly, but when I walk into
some online servers to run, it gives me a
message that the LFS.exe falls and if I want to close or
seek solutions on the Internet, and that normal, not before
case with Windows XP, what should I do about it,
something missing, some setup.

Have you tried reinstalling LFS?
