Ok. so here's an update
I spoke with Moto's customer service. They had me to clear data in the webtop connector, desktop home, cardock and entertainment center app. Nothing worked. I even cleared the cache going thru android boot. (Still nothing). I have changed the SIM card and verified that the HDMI port is working.
So, my next and last step was to do a hard reset.
Well, after the hard reset, my webtop is working again. (Praise God). I'm still reinstalling all my apps, and no problems with webtop after a week or so.
