messed up my phone

[10smom]

Here is my dilima: I have owned my treo for about two months. I have been trying to figure out the best way to get my contacts from outlook onto my treo and then onto my mac address book. I have been syning with Missing Sync for about 1 month and lost the few contacts I had on Mac address book from syncing after I did the last Verizion update. I decided to bite the bullet and just hook up my Treo to my Desktop PC and sync with Palm Software to get my Contacts from Outlook onto treo. Well that totaly messed up my phone. I do have my 3 years worth of contacts finally on My Treo but now I cannot syn with my Mac. the Mac is not seeing it. Even worsse, cannot recieve calls I can call out though. I get this error chime saying there is no service. Any suggestion would be greatly appreciated it. I Would prefer not to have to delete my contacts, but I really do need to be syncing with my Mac. Thanks for you help.
