8703e Iusacell download problems

Guys, I searched the forum for help on this, but no luck.. Someone stole my Storm, so I replaced it with an 8703e (temporarily):mad:. It's a new CDMA Unlocked phone.. I activated it yesterday. Phone and text work, no email... My carrier is Iusacell and they are of no help. I downloaded the .exe file for Iusacell, but can't get to work. Any suggestions? Apparently if I can get this update working, I'm back in business!

FYI. I downloaded and ran it, but when I search for updates with Desktop Mgr, nothing comes up. I tried to uninstall and download again and nothing! Also tried to browse, but no app files are in my computer..:confused:
Thanks in advance for your help!
