I'm suddenly having trouble with my tablet (Huion H610PRO (8192)). The pen's been going for a while and only works while its plugged in, but it suddenly stopped picking up not too long after finishing my recent pic. Tried restarting, installing new drivers installing the driver in the CD that came with it and now its saying its disconnected even though the buttons work and are picked up on the PC. The light is on inside the pen so I assume thats still working, just wondering if anyone knows anything about it?
