So even though SimTower worked fine (on XP) while I built my first tower, it now freaks out and has to close 5 seconds after loading my second one. And this is after restarting a couple times and not running the program for a week or two. I don’t know … maybe I installed something to provoke the error, but if I did, I wouldn’t have any way of finding out what. Eh … maybe SimTower is dead. Despite all the time spent playing it while I was younger, I guess it won’t work forever. Why did Maxis only release one version?
