Ok let me make it clear by starting from the beggining.
I played the game on the 1st pc (Intel 2.8GHz, Radeon 9700, 512MB etc...). I had no problems.
Installed the game on the 2nd pc (Athlon 2400XP, NVidia GeForce4800 ti, 512MB etc...) and copied the saved games from the 1st pc. It didnt load the saved games so I started a new one (still on the 2nd pc). This is were the problems started. The problems I had at that point is that sometimes I couldnt load a saved gamed, and sometimes it was crashing when I was saving the game. So I installed the patch (just in case is fixes it). I loaded the last saved game without a problem and continued playing it. So I was playing the game as before, loading and saving (everytime on a new name) with the occasional problems when saving and loading, until I reached a point where it was crashing at random places. There is a point though that is crashing every time. That is when I try to enter the castle to meet the boy Duke for the first time.
Let me note that when I realised that the saved games from the 1st pc dont load, I deleted them completely from my pc just in case they create any problems to the new game.

I hope I made it a bit clearer <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
