Help! Calendar not working

[bluedukies8]

I have a 3g on 3.1.2 jb. I ssh'd to change the calendar colors and used sqlitebrowser to edit the colors. Copied the new updated file back onto the iphone and everything seemed ok, but now my calendar won't work. Doesn't update to show new appointments. I have even tried to delete the exchange calendar for work and my google calendar. Neither will delete from the phone.

Does anybody have any suggestions on what I can do? Or does anyone have the "stock" calendar file that I could ssh in? I thought I had a copy of it but I don't.

Any help would be great!

I use a PC too if that helps.
