wacom intuos small pen not clicking?

NEVERMIND I SMACKED THE PEN AND IT STARTED WORKING SOMEHOW

----

i'm using a wacom intuos small (CLT4100) and then the pen nib stopped clicking? the pen hovers, and the buttons on the side work just fine, it's only the pen tip doesn't do anything.

i was in krita at the time it stopped, and it doesn't work anywhere else either, so i can't do any left clicks unless i assign a side button to it. oddly enough, the pressure registers when i test it in wacom tablet properties, but the pen tip still doesn't click? i've tried replacing the pen nib, and my driver is up to date. also, my operating system is windows 7.

i'm thinking it's a problem with the pen itself since my tablet's buttons still work, but i'm not sure.
