Help please?

Hullo. c: I just recently got my beautiful new tablet at christmas {Genius tablet} and it's been working fine except once or twice it's done this before.
Suddenly when I'm on GIMP {2}, the pen pressure is working smoothly and then it just stops. Sometimes if I unplug the tablet and then plug it back in it works or refresh the page, but this time none of that's working. ._.
Anyone got any suggestions?
{the tablet's already installed, etc}
Thanks,
