pro8 not charging from Pro8 Docking Station

I have a Dell Venue 8. It is nice and I have the plugable Pro8 Docking Station - it is worth every penny (if it will start charging the tablet).

The station will not charge the tablet though. The tablet charges fine from the wall… just not from the docking station.

We are getting ready to move to Nicaragua soon… Please help so I can enjoy my tablet and docking station there!
