Gerald, Eric I tried removing, downloading and installing Preview 12 again yesterday. After shutting down the computer and restarting, I was again presented with the fatal error and messages I e-mailed you when start-up reached "Loading Main Form".
I then renamed 'command_memory.txt' and 'PowerSDR.mdb' and restarted Preview 12 which brought up the wizard. In wizard, I imported PowerSDR.mdb from the Preview 8 folder and Preview 12 ran OK. Shut down and re-started the computer then started Preview 12 and it came back OK without the fatal error I had been getting when start-up reached "Loading Main Form". All of the settings I had in Preview 8 were imported OK and Preview 12 runs with no problem every time I start up. Until this version, all I had to do was copy 'command_memory.txt' and 'PowerSDR.mdb' from the folder containing the previously working version into the folder where the new version was installed, start-up and run the new version.
