VCMP needs a clean version of VC. Ofc. some elements can be modded, like car look, but not his handling. After you installed a clean copy of VC, you can make a copy of it and call it "VC modded" or something.
If you don't see any server at "Internet" tab, you have or some Internet problems or you have installed a wrong version of VCMP. I have a list of server, maybe try again now to refresh it.
