LOGic 9 has worked well for a long time on my Win-10 64 bit machine, but every time Win-10 updates itself, I often have problems with Ham Radio problems. Now it's LOGic.

Yesterday when I tried to start LOGic, I got an error message: "Microsoft Visual Fox Pro. Wrong version of Callsign Exception File." I clicked [OK} and got another error message: "Error 2059 'Unhandled Structured Exception>' Error No: 2071, Message: User thrown error." User Value: Prefix lookup setup failed. Details Procedure: prefixlookupsetup Line No: 24 'has occurred in program, line0. Attempt to continue" I then clicked [OK] and nothing happened and LOGic didn't start. I've rebooted and "restored" my computer to a previous date but that didn't work. I just tried to reinstall LOGic 9 from the original CD and got the same errors and no start.

The word "prefix" might be related to me adding another user defined selection in my log screen; I added "PFX" but I've been using that for a month without problems.

Please help;

Thanks, Joe, NA9A #5717
