You used the web-based OS upgrade. I have yet to use that.
I would try using the link ZeroG posted and download AND install the OS to your PC. Use JL_Cmder to wipe your device, you should be left with a 507 error indicating you don't have any OS loaded onto your blackberry.
From there, connect your device to DM and run through the installation, make sure to check all the applications you want to install, such as Docs to Go.
Be sure to do a backup before you do these steps.
