Cannot edit game in database

[Radiant]

I've tried adding a game to the database, and received an error page, something with "error writing file".

Turns out the game is added anyway, but the credits section is not. This means I'm unable to modify the entry, as it's not assigned to me. Can someone fix this please?

Done.  The games page will be fixed soon!
