New cgminer.exe is failing with "cgminer.exe is not a valid win32 application".
This is embarassing, the file got currupted during copy. Please redownload.
Redownloaded, now getting "Access is denied" when executing. Beta is still working fine and I ran from administrative command prompt.
Must be the old one cached somewhere, I have tested that current download works. Renamed the file just in case.
