Instructions on how to use the signature checker should be on the site. Simply clicking the file won\'t do the job.
If you use a download accelerator you\'re more likely to end up with corrupted files than if you simply used the default Windows downloader.
Also, redownload the run_me_first.bat file. It may be that this itself is causing the problem.
That\'s all I can think of right now, hope something there helps.
