Used xBackup on PDA2K and now contacts are GONE

[twn2]

This is strange....I used xBackup yesterday on my PDA2k (which took about 30 minutes) to backup to my SD card and a while later I went to look for a contact and all my contacts are gone. Everything else is there, just my contacts vanished. My backup file is 22mb. I tried a soft reset and that didn't help. My contacts are on my PC but this is a rather strange issue. I selected a system backup rather than a Contacts and Appt backup.

Does anyone know what file holds contacts so I can see the size? I haven't done a sync yet because I want to try to find out why this problem happened.

Any thoughts?

Thanks,
Tom
