I'm glad you were able to solve your own problem, but you didn't share the solution with the rest of us.... LOL
I had another issue (one relating to Crypt Magic not working on my 8310, even though it was working on the 8300), and I have this solution:
Go to:
BlackBerry Operating System Downloads - BlackBerryFAQ
Click on the link for your country and carrier. In my case, USA, AT&T:
https://www.blackberry.com/Downloads...E4F82F9F00E7D4
In the drop down menu, choose the Blackberry Curve 8300
Scroll down, click on download the software. That took me to:
https://www.blackberry.com/Downloads...D615A00DD50DAD
The download updates the Blackberry Desktop Manager, and makes it possible to load applications on the 8300.
I hope that helps.
(I also hope that all of my information is correct)
