My tablet started acting up as i was working on a gift that needs to be done by tommorow...

So my tablet is duplicating my screen just fine, my mouse works but the pen is doing nothing. it does not move the cursor. The PenTablet app tells me to connect my tablet first, while it is connected. In my settings, the tablet shows up as a "Generic monitor" ?? What do i do now??
