Like I stated, I was confused also. The titile bar on the error box identified the program as the Alpha3. The program identified itself as v3.07 Beta. If 3.07 is expired, as yoy say, why is there no replacement on the website? V3.07 Beta is the NEWEST version offered on the website!
Like I said, doing a repair on .NET and installing the latest version of Windows Installer allowed me to do a complete install. Thank you for a very nice program.
