Nexstar crisis?

So I purchased a Nexstar CX.
And I am having problems with it.

On my computer it reads Nexstar E
on my television (it only now started to read C) is reads Nexstar C

It takes a while to load the movie on to my computer.
And It takes forever to load a movie from my computer on to the Nexstar… Both using Windows and Terracopy.

I downloaded Driver Boost…didn’t run it yet…not sure If that is the solution.
Was wondering IF anyone else had this problem…and why am I having the problem…how can it be fixed?
