Tips for hard difficulty?

[Nuvag]

Lost the original Logfile when clicking "verifying game cache", but could reproduce the errors and attached the Logfile.

I receive "error: no such database: origin" every single time i save a game, except very rarely when i receive the other one ("error: unable to close due to unfinalized statements or unfinished backups")

However everything seems fine, i can save and load the Savegames and just continue the game.
