Hmm, almost missed that. I'll echo Dedas: Happy Birthday, Gandalf!

khaal, I meant that if you were to zip up one of these game folders and send it to IW, they could perhaps glean something from it. If not, then it's time to check what Gandalf and Arralen mentioned here and also see if all the necessary library files on your Linux install are up to date. Wrong libraries cause problems, I've been given to understand. You'll need to ask someone else for Linux advice, though, I'm not just a newbie but an actual n00b with that OS (almost any distro).
