Chuck, did you read the FAQ link I gave you, which answers specifically what to do in response to the error message?
heck, I will copy it here: QUESTION
When I use Application Loader from with Desktop Manager, I get the error "No additional applications designed for your device were found." ANSWER:
You must have the current handheld operating system loaded to your PC as well, when you attempt to load other applications. The handheld OS on your PC must match the handheld OS on your BlackBerry, or you will be asked to upgrade to the OS installed to your PC.
Find your current BlackBerry handheld OS on your BlackBerry by looking at Options > About. Normally the third line or the line that begins with "v."
Find and download your OS here: BlackBerry Operating System Downloads - BlackBerryFAQ
Also, make sure you have downloaded and are using the most recent version of Desktop Manager. BlackBerry Desktop Manager Downloads - BlackBerryFAQ
