Does anyone have a copy a pre v4.1 version of the handheld and desktop software?

I recently upgraded to 4.1 and now i can't load my address book that i backed up prior to the upgrade. Aparently, v4.1 requires certain fields to be mandatory in the address (first name, lastname, etc) and does not allow certian characters in the name fields. So if you have ANY addresses in your address book does not conform to the above you will NOT be able to import any of the addresses from your address book!!!!

I am trying to track down prior versions of the software to DOWNGRADE so that i can load up my address book.

Any help would be greatly appreciated!!
