Sync promblems HELP!!!!

I sure hope that there is someone out there that can help me out with this. I use Outlook 2003 and everything has worked great with my BB. I went to sync today and it erased all my past appoinments and I can't get them back (I learned my lesson on watching what is added and deleted now). Now it wants to delete future appoinments. Is there any way to fix this so that it just keeps all files unless I make a change? And is there any way to get those old files back?

I did the system upgrade the other day. I've tried to restore my computer but it doesn't restore personal files.

HELP!!!

Just so everyone knows I have made contact with my carrier (verizon). We got my old appoinments back on through the deleted files in Outlook. Still having problems with the sync of the future appointments. Verizon is calling BB and I hope to get it all figured out. :confused:
