Or try deleting a few races before deleting the whole campaign.
If this is a general problem, I'll create a version of the patch with no example game.
I managed to delete the game with this method. I deleted every race but one in SM mode, set it as default, left and deleted the game.
However the database size is still 172 MB so I wonder if I actually did it right. Any help on that would be appreciated before I seriously start a game..
And trying the compact database command doesn't work either. I don't even know if this command is supposed to work or not though.
I get a
Runtime Error 429 - ActiveX Component Can't Create Object
followed by infinite error 3420s
