You, like, install the 1.5 patch.

I recall having to download a multitude of other patches, fixes, and files to restore it, which wasn't my idea of fun, and I haven't played it since 1.5 was released.

To go from the original US retail to TWEE:DC
1. Patch to whatever the latest version is. It should be a single patch
2. Patch to the Director's Cut (uncensored). Again, a single patch.
3. Install Side Effects and The Price of Neutrality (the bonus adventures)
So four executables to run. And, depending on where you get TWEE:DC from, you'll have to do step 3 anyway (so far, the GamersGate version is the only EE I have seen that doesn't use seperate installers for those two adventures).

Aye, I remember that. A while ago, bit still was a pain in the ass. I remember something about having to email this dude to receive the uncensored files.

??? Nor sure what you're on about, but the patches (and there aren't that many of them) are quite easy to find.

I was talking about getting the uncensored files via the steps outlined in this thread. Back when version 1.4 (EE North American/U.S Box release) was the newest release over here

This was back in 2008 or something like that.
Thankfully the developers released an easier way to do it all :D
All I need now is the directorscutpatch.exe and TheWitcherPatch.1.5.exe :)
