problem syncing..

[Prepjim]

I formatted my computer and lost all my contacts in outlook.
whenever I sync my touch to my computer it deletes all my contacts on my phone(thankfully, i backed up with spb backup)

what im trying to accomplish is transfer my phonebook to microsoft outlook.
ive tried replace items on device and desktop and still no luck

When i sync it shows windows pc & windows pc2 and tells me i need to delete one.

pls help!!!
