[jp] Datebook not synced

Hi!

For some unknown reason J-Pilot has stopped syncing my datebook. The 
print-out says:

"Syncing DatebookDB fast_sync_application: Unable to open file: DatebookDB"

The To-do's, Contacts and Memos are synced properly.

I would be grateful for advice as to how to solve this problem.

Thanks!
