This weekend I attempted to

This weekend I attempted to back up my iPAQ, by copying and pasting the contents of my Memory and Storage card to my desktop via USB, which worked just fine - other methods don't seem to work, and I have been unable to Sync.

This morning I used my "Contacts" and "Calendar" although it did look "different" (it has gone "American"). I noticed that my "tasks" / "contacts" and "calendar" were "empty", and after doing a soft restart, they returned for a while, but I appeared to have many programs in duplicate - ie the Programs list shows many programs twice (the second one having (1) after it. Then I noticed issues with insufficient memory so I closed all running programs. After this the contacts and calendar buttons don't execute the command, and I believe the information is there, but I don't know how to access it - HELP! The information must be safe somewhere (even if only on my desktop computer "backup"). I've also noticed that all of my Excel / Word documents (which are still visible), are not associated with the original programs, and I cannot open them within the appropriate program as help suggests (as there is no option to do this). I've even got two "Time's" on the today screen, which are showning DIFFERENT time's. It's as though my iPAQ has a split personality, and I want the other one! PLEASE Help me.
