I assume by "no Luck" you mean you got the same error message:

E609: Cscope error: cscope: cannot read trailer offset from file .\cscope.out

I won't be able to try any experiments with this myself until
tomorrow, when I'll have access to a system with cscope. In the
mean time, you might try Cygwin's vim and see if that makes a
difference. You might also try creating a minimal source tree that
exhibits the problem and that others on this list could use to
replicate or help identify the problem.

Also, it's customary on this list to put your message at the bottom,
rather than at the top, of a reply.
