I suppose you're all getting tired of questions like this one, but I love this old classic and I really want to play it once more, so please bear with me

Well, I actually got KQ7 to run under Win2k, using all sorts of troubleshooting guides from the web, but unfortunately I couldn't find any help on how to fix the speed problem.
When I start the game up, I get the crown cursor and the start screen, but the music and animation are intolerably slow. It's like I'm running the game in extra slow motion. I don't even know if the actual gameplay is slowed down as well because I never got around the first cutscene with Valanice, I always aborted before because her voice acting sounds like Rammstein performing a ballad...
I suppose it's a memory problem since I also get a strange message when doing the memory test in the installation prog, telling me I don't have enough memory which is quite impossible.
I'm running Windows 2000 SP4 on a 1GHz Pentium with 129.520 KB RAM
Can anyone help me?
Thanks in advance!
