It happend again!

The batteri gone empty and I had to reinstall all the programs on my Axim X50v. Worse case is that when I sync my PPC with Outlook om my PC, it took away all I had booked in for the next 2 weeks (I lost the data). My back-up was 3 weeks old, so there were no help there. So to the puzzel Dell could not find a solution for: The PPC still come up with warnings about apointments I asumed were lost. Where is the file for this warnings?

It`s not the back-up file, and I will be wery happy if somebode can tell me were to find this file on my PPC, so I can restore the lost apointments.
