Kontrol X1 problems

I got a Kontrol X1 a few years back to use when I dj in Europe because it is easier to pack than my S4. But lately some of the buttons stick (like the cue and play etc). I've switched usb cables, and I have Traktor updated and everything. I don't know if it's just a little beat up from being in the heat from the beach bars or what. Do I just get a new one? or is it a software issue? I am still using an older mac, I don't know if that's an issue or not.

thanks in advance!
