I just installed Windows XP Service Pack 1. Since then I cannot get MS FS2002 to open. I get the error message: "FS 2002 has detected 3rd party software that may not be compatible." - traffic.dll. However, I have NOT downloaded or install ANY third party software. Then the uninstall shield would not work, so I had to manually delete the program to reinstall. Reinstalled and still get the problem. The XP info said that it may affect some programs, so I accepted the option to back up files so XP Ser Pack 1 could be deleted and go back to the previous version. Haven't done this yet. Has anyone heard of this problem? FS2002 seems to be the only program affected so far.
