Glad you got it working. <img src="/ubbthreads/images/graemlins/party.gif" alt="" />
You should just be able to copy the game from your current PC to the new one, assuming they will be networked or you are just transferring the hard drive. The registry entries the installer creates (described in the manual install procedure) are only required so the patch can find the install path, and are not required if you have installed the patch on your current system, or have an already updated re-release version of the game (ie 1.0034A shown in the bottom right corner of the main menu).
