my tablet have stopped being sensitive ... does not matter how many times I unplug it and plug it back to my comp

waaaaaaaah sniff

I have been trying to locate it in the hard drive to see if it only need an update but how much I search I can't find it
and I was so happy to get one for free (for drawing a free pic in return)
I don't know if it only needs to be replaced with a new "stift" to the pen ... but I can't seem to find the brand Trust in sweden ... I can locate the others but not that one

I guess I need to find a cheap drawing tablet with similar size on the screen to draw on *mutters* but it is another item on the list I have to save money for >.<
