Syncing cannot be completed

[Singaporeuser]

I upgraded the ROM. But after that, whenever i try to sync, it tells me that syncing cannot be completed and i have to disconnect my device and try again later. And to go the AS Help (that goes a non-existent page).

This is what happens when i connect my device to the desktop. it starts syncing as usual...but the progress bar movement is quite slow...

midway thru syncing, a message appears that some items on the pda have never been sync-ed with the desktop (or something like that) and 3 options appear w/r to (1) combine the items in the desktop with the pda (2) replace those in pda with those in desktop or (3) not syncing them at the moment.

I tried (1) and (3) before ... and the syncing continues, but the progress bar, after a while more, never reaches the end. It just stops syncing and the message abt syncing cannot be completed appears.

I've tried these but cannot work:
- hard reset
- uninstal AS and reinstall + upgrade to 3.6
- delete partnership/ reestab partnership

but nothing works! If there's a conflict i dunno what there can be cos i only have adobe acrobat added to what was in the Axim originally! The rest are doc files/ contact list/ mp3s?!?!?

Anyone can help? I've posted this on other sites too.. hopefully i get can some help on this from somewhere!
