Restoring Entourage database

[DavidP]

I have a PowerBook 15" G4 running Entourage 2004. I recently got a Blackberry Pearl that I have been synchronising with my Mac using the PocketMac Synch Manager. When synching it has been bringing up reminders of meetings that occurred up to 3 years ago and asking me what to do. As I thought it was only the reminder for these meetings I have been selecting "Delete from Mac" from the options available.

Today I had to check details of a meeting last year and found that all Calendar events have been deleted from Entourage prior to January this year. I've been backing up to an external drive and found a copy of the Entourage database from December 2007. I've transferred this Database to my hard drive, but can't work out how to restore the database from this file. When I hold down Option and start Entourage I only get options to rebuild the database from the Main Identity backed up today. Other identities that I can see give me an error message that "There is no such disk".

Can anyone tell me how I can get Entourage to load the old database file to Entourage? If the rebuild overwrites the current data I assume I can then Synch again from my Blackberry to get meetings since December...

Any assistance much appreciated!
