Unable to create a user waypoint.

[snakekiller1x95]

Hi, Plan-G is an amazing software, except that every time I try to create a waypoint, it says "Sorry, I was unable to create the waypoint. Please see the log file for the details. " I also can't find the log file, so I have no idea how to solve the problem. Help would be deeply appreciated.
Thank you

The log file is in the same folder as plan-g.exe.

reinstalled Plan-G and it all works fine now. No idea though why I had the problem.
