Gothic 3 Insert CD/DVD problem

Hello,
I have a problem with insert CD/DVD... i have bought the game today.. and i tried it with no patch.. it works.. but there is too many annoying bugs.. so i did install patch 1.12 to get better playing experience.. after the install i tryed to start the game...... a screen with litterng Gothic 3 popped up but then popped an Error with sentence "Please insert the Gothic III CD/DVD into your drive and start the game again. Do not remove the disc while playing." I´ve tried to find some responses on net.. but i couldnt find any which could help me... yes.. i tried reinstall the game many times... but still the same error.. does anybody know how to fix this please ? thanks for any responses..

yes i did try that already... i´ve read something about that.. but still dont works at all...

The latest community patch (1.5.2, I believe?) removes the copyprotection - it should fix your problems.

Oh really.. it works thanks you..

The problem was that you were using the Gothic Universe edition.

Even didnt know that :-O .... but thanks a lot to all that wanted to help me... i wish nice playing ;-)
