I just got a new computer. And I need help transferring my saved game files from VV3 since I bought it online and did not get a game CD. I am pretty sure both the computers run on Windows Vista. But I don't know how to install VV3 on my new computer without buying it again. I don't have the registration code either, if that is of any relevance.

I need help. X___X

You don't have to buy the game again, although the method that you will use to install and activate it will depend upon where you originally purchased it.
