Ron, if you still have the VersaPro CD, you can uninstall the software and then reinstall. Either that or someone has transferrede the license to a different computer without Ron's knowledge.
If the license hasn't been moved to a different sector of the hard drive during a defrag operation, then the sector where the license is located may be corrupted. It sounds like the software's license manager can't find the license for some reason. If you have a licensed version, you never get that message. When you start VersaPro after the trail period has expired, you get the message that Ron saw. After the four-day period, you can no longer create new project files or modify existing ones unless you get a license. During that trial period, the software is fully functional with no limitations on program size or communications capability. When you install VersaPro without a license you start a four-day trial period.
