If you are running XP, try the compatability modes (98/ME first) and if that doesnt work, it could be a corrupted file and you have to redownload. If you have to redownload, use the MD5 signature checker tool or you can download the new
run_me_first.bat file that has it built in.
As well, if you have to redownload, make sure you aren\'t using a download accelerator as they tend to corrupt files during download.
