It seems I have some explaining to do. Excuse me for leaving that part out - I live in Estonia.
In the meantime I have been really wanting to get the game running again and I have found the problem and also a solution for it.
For some reason I did not notice the fact that I was always trying to start the game using the shortcut on my desktop - when I did now try to start it using the executable then I came to find that it was working just fine.
I tried it several times and confirmed that every time I tried starting the game using the executable 'gish.exe' in the installation folder the game started normally. Therefore I concluded that the problem had to be with the shortcut. I checked its 'Properties' - the target folder was correct but in the "Start in:"-field there was 'G:\Games\GISH\tile07', which was odd for me... I changed it to my default installation folder (G:\Games\GISH) and tried starting the game - voila - works fine, problem solved.
Sorry for the confusion and thanks for your helpfulness and quick reply.
