Well after a few days of not syncing, I was getting pretty frustrated. Then, this morning, my daughter logged on to her account in Windows XP, and my Ax started syncing with her account. So I don't know exactly how that happened, but I took advantage of the opportunity to do a full back-up. Then I deleted the partnership from her account. I logged out of her account, logged into my own. Tried to sync, and it told me the partnership already existed and to choose a new name. SO I removed my AX, deleted the partnership from my account, put the ax back int, and recreated the partnership. It seems to have worked fine, and is working now.
I had done many soft resets, but I had yet to reinstall active sync cause I was afraid I would mess something up especially cause I didn't have a recent full back-up anywhere.
So it looks like deleting the partnership from all the accounts on the computer seems to have worked. And I didn't have to reinstall anything.
I don't know what caused the problem in the first place, but hopefully it won't happen again!!
Hope that helps anybody else out there with a similar problem. Try just deleting the partnership (without deleting the files folder) and see if that works!
