MC2 is really old. Are you sure the program will actually run on the computer you have now? Unless you have a computer with a compatible OS, you might not be able to get it to run properly even after getting the VST adapter.
I'm not a salesman for Cake, however, I would seriously recommend an upgrade to MC7... the latest version. They have done so many nice things to the software since MC2 was new. The synths in the newer versions alone are worth the upgrade price. $50 in the store. And everything you need is there, ready to go and start making music.
