Can't access secret door to Falrinth

[Serethos]

In dungeon level 3 there is a round room with a hidden trap door which leads to the rooms of Falrinth. But my problem is that like the loot bug a hand-symbol appears but clicking on the door does nothing. I have a German version from a PC Magazine and noticed that all patches (also the _all-Versions) do not function for my game. After patching (sometime saying that some file in the original installation is missing) the game won't start. So if it is the same like the loot-bug I can't fix it via patch ..

any ideas?

Minor spoilers. Highlight to read.

Some people have this problem, but it's not related to the looting bug. Anyway, the simplest workaround is to go through to that area from the other side. From the front of the temple (outside), go right and go through the tower, where a large battle with guardsmen will leave you with a room full of corpses, a chest, and a secret door. That door will lead to a tunnel that will lead (when you go right) to the area where Falrinth resides. AFAIK, those who have your problem can find the door from the other side. And even if you can't, you can just go the long way. The door's just a shortcut.
