I have just found that after resetting my server computer. TWGS has lost all its settings.. including registration, show once pages, games and their settings... everything. I noticed that TWGS does NOT retain these settings even after simply closing and rerunning the program.
Other software, such as swath, teamspeak, etc are running fine.

Anyone else running windows 8 have any suggestions, apart from finding another operating system?

Thanks.

Have you tried running it as an administrator?
It is possible that the settings are not being saved because of permissions to the locations where this information is stored.

Sorry I found the problem and mentioned it in another thread... I needed to run it using xp service pack 3 compatibility mode.. it all seems good now.
Thanks.
