BB Torch :: 9800 Fails After Downlowding Wirelessly?

I need to reinstall version 6.0. I made the mistake of downloading it to my Torch 9800 and something went wrong since now my contacts do not synch via my enterprise server. Other functions freeze when try to use them. I have spent hours on the phone with AT&T, later with Data Group and finally with Blackberry directly. The last technician at BB sent me to open http://www.blackberry.com/btsc/KB11320 so that I could perform a clean reload of the BlackBerry Device Software for Windows. I followed those instructions carefully. When choosing to Update my device, which should give me the option to reload, it simply tells me that there are no new updates. Calling AT&T is a waste of time because they want to do the whole procedure all over (hours) or I receive their emails telling me that I must have the wrong version If anyone knows how to reinstall version 6.0 I will certainly otherwise I'll try to ask them to replace the phone.
