Well, once you DO get an internet connection, you should download the entire Witcher 2 EE game (from GOG - in your game account) and do a fresh reinstall, anyway. That way you will be sure of having a good, clean install and will not have to suffer through any possible weird glitches that patching and upgrading can cause.
If you didn't originally get the game from GOG - check the witcher.com page for how to do just that

Good luck!
