So I recently wiped my pc and reinstalled Windows, again. I have also wiped my other pcs and brothers pc a couple times (viruses, windows boot errors, system upgrades). Today I get a message saying my keys have all been used. Well obviously Startisback deesn't know that I've wiped and reinstalled. Is there a way to deactivate all the pcs so I can activate the ones ataully being used? I have the 5 user pack.
