Blackberry Desktop Software cannot communicate with connected device

Hey!

As the title says my bb won't connect with bb desktop manager for some reason, now i have been looking all around google for like 2 hours and havent find anything yet. I've seen something about wireless update but it's not on my phone. I have already tryed to update it but it doesnt work it keeps loading but it doesnt do anything... Here a image of the error not my phone but i get the same error -



It also says view other versions but it doesnt say that on my desktop manager when i plugin my bb. It only says 'Retry, Update and Exit'. What i'm doing wrong? Please help me!

:D
