Please help touchscreen not working

[cmoney12051]

I recently bought what I thought was an irobot off ebay. When I got it I found out it was just a generic 7inch MID with a via chipset. But before I foundh this out I tried to update the firmware to the slatedroid1.3 custom firmware. It updated but now the touchscreen is not working. Does anyone know of a firmware that I can put on this thing to get the touchscreen back. I have been able to hook a mouse and keyboard up and try to calibrate the screen again but no luck. So if anyone knows of a good solution id really apreciate it. Thanks
