I'm having a similar problem to Skiddie. I received my BB a few days ago, and it was running ver 1.0. I had a requirement to keep and RDP session alive, and the infinateControl payload worked great (i.e.presses CTRL every 10 seconds).
I upgraded to ver 1.1 and this no longer works. I think it may be something to do with the language. The languages folder is empty, and I've been trying to get hold of the gb.json file. I've downloaded the ducktoolkit from the link above, but as far as I can see there is no language folder within the tarball.
Any suggestions?
