Query: Zune Software Ver. 2.0 Problem

I bought(2)of this unit within one month. Because the 1st one was using Ver 1.0 Software, it was great, so easy to managed & transfer files....So I decide to get a 2nd one that when Microsoft "UPGRADE!!!" the software to Ver.2.0 , Now I have (2) unit & stuck with their "STUPID UPGRAGE!!!" .So don't buy this until they fix the software problems or smart enough to repost Ver. 1.0 .*PS: "UPGRADE Ver. 2.0 NOT WORKING WITH WINDOWS VISTA EITHER!!!"
