I have Vista and had issues getting it to run. I would get all the way to the 'pick a character' screen, then it would look like it was going to let me in and would just hang there with the main screen black. I could see the side panel, but none of the packs were showing up.
First off, don't install AC in the default directory. Use something like: C:\GAMES\Asherons Call.
Second, make sure your AV program doesn't conflict with the game. I was using AVG and had to completely remove any AV program, otherwise it wouldn't let me get IG.
Third, I had to open ports 9000-9030 on my router (I had to forward those ports to my local computer).
Once I did all that, I was able to get IG.
Remember, your mileage may vary.....
