UTrack Remote via Wireless still not working

I just bought a new Tablet by Lenovo, and I actually got it running once today, but never again. The settings tell me it’s connected, I typed in what looks to be the right info, but the software –U-remote only stays in demo mode. There’s gotta be some bugs in this software or something. What am I doing wrong. Do I need to do something with the software to set it up? I’m baffelled and bummed out. Marc Trainor.
