I am having difficulty using the Application Loader tool in the Blackberry Desktop Manager software. Whenever I open the Application Loader, I get the following message:

"No system software was found for your handheld.
Contact your system administrator or service profider for information on obtaining handheld system software."

I am using version 3.6.3.10 of the Desktop Manager software (what came on the CD with my device).

My Blackberry has version 3.8.0.128 (Platform 1.8.0.9.1), Cryptographic Kernel 3.8.0.18

Does anyone know what I am doing wrong here? Thanks in advance for any help!
