Photoshop start having problems.

Hi,

I've been using Photoshop for a year daily with my drawing tablet (Wacom Intuos comic) and it's been a great year. But this week, I started doing a comic and for some reason, when I try to draw, it will draw for like only 15 s or so. So I was like, maybe it's a bug. So I restarted Photoshop and it's doing that not only with the brush and pen, but with every other things (eraser, moving around, zooming, etc) so I don't know if it's my Photoshop or if it's my tablet that's not working. It work with the mouse too perfectly ! It's weird.

Thanks
