whenever i go to an airport that has project ai traffic i get an error message saying that MSFS has encountered an error and needs to be restarted. i do this and the cycle starts all over again. do i need to download something else like taxispeed?

Is there more to the error message, such as a Send/Don't Send? If so, click on the dark blue more information line and see what module is causing the problem. If you can provide more detail, it might be easier to troubleshoot.What happens when you start FS2002 at an airport that has a lot of AI aircraft, same problem or different?Taxispeed isn't going to fix the problem. Have you tried lowering the percentage of AI to see if it fixes your problem?
