My pen doesn't want to work in Photoshop

One moment I was normally drawing in Photoshop CC 217, the next my pen suddenly stopped working - by that I mean that it still "draws", but no matter what function I select, it only works as ereaser in one size. On the other hand, when I tried my mouse/touchpad, it worked perfectly fine. I can't draw with mouse though, so is there a way to fix it? The pen works fine in other drawing programs. If it is of any help, my tablet is Huion NEW 1060PLUS.
