activesync conflict

[PBeatty]

i am having great difficulty with activesync and my new 2210. my pc seems unable to convert any word files to put them onto my pda. it did work the other way, until i deselected some of the files from the sync list. nxt sync these were erased from both machines, and when i restored them from my pc's rubbish bin, they couldnt be synced onto my pda again. also, one file i have been unable to send from pc to pda, i was able to beam from another pda to mine, but when next syncing it was erased.

whats going on?
any help greatly appreciated as this is really hacking me off and its only a matter of time till i lose some important info.
