Help ! I have moved to 3.7.8 and while the games are here, all the maps have gone. No map=no game. Ideas?

Help. I have upped to 3.7.8 to keep pace with my opponents, the module library has my various games listed, but no maps or boards appear, I get as far as “start new log file” and there it stops, I get returned to module library. I have read other forum posts carefully, yes I have moved to OS Sonoma 14/3 but nothing seems to work. Looking bad for the current Holland 44 game I have in progress. Ideas?

Please describe in more detail what you’re doing and seeing, or provide screenshots. What does “returned to module library” mean?

Are there any error dialogs? If so, what messages are in them?
