I just updated to the new OS, and now I can't open Date and Time nor the clock.

When I tap Date and Time in the Control Panel, it says that the "device is full", yet I have like 80MBs free. All the other panels open fine.

The Clock wouldn't open either. When I try opening it, it just says "Application failed".

I figured this could be something to do with my previous mod to add Toronto to the city list, so I copied my modified osso-cities.mo back, yet it didn't fix it.

How can I fix this?

Fixed it, forgot to copy back the wdb-parsed.txt.
