I agree that the Big Fish Client can be buggy, and it's probably buggiest on older computers that have had many different versions of the Big Fish Client installed and many different games played on them over the years.
I'm sorry no one here really has an answer for you - not for all your issues anyway.
#Need to reinstall big fish game manager install
It will download and install it but wont run it. And if I quit a demo I have to reboot before buying the full game because otherwise the game manager wont run the newly installed full version. The game manager wont run the game again until I reboot. Same thing happens if I quit an unfinished game then try to reload it later. Only way I can delete the game is to reboot the computer. Lately Big Fish games are apparently not completing shutting down because whenever I finish a game and exit out the game manger claims the game is still running when I try to delete it. Re: Big Fish games leaving something running This happens because the Big Fish client is trying to keep track of all your installed games and objects to something suddenly disappearing from its list without its permission - at least while the Client is running and active. This also happens after I install a game - I can't move the game folder of that or any other game without first doing something (like rebooting) to make sure the Game Manager is closed. In my experience, if I started a game - any Big Fish game - using the shortcut Big Fish creates, the Game Manager never completely closes after exiting the game and blocks me from moving any Big Fish game folder, not just the game I was just playing. If you try to move or manually delete a game folder while the Game Manager is running, you'll get a "file or folder in use" type problem. There are other ways to uninstall where there is a "file or folder in use" problem if the Game Manager is running. If you uninstall through the Game Manager there shouldn't be a problem.
