Or here, found another way to fix it as long as you have a key product and email that it was registered under. Is the most simple I figured out after going thru the whole deleting 435235329459284 keys it had
on registry go to :
KHKEY_LOCAL_MACHINE/Software/Reensoft/PIEPlus
once there u have to create two "string" values called :
"RegCode" with value data of the serial number of course......and
"RegEmail" with value data as the email address used when u(or a friend) purchased the item
and VIVA LA PIEPlus
might be confusing the way I exlpained it, so I apologize if it is, but understand i spent hours playing with the registry trygin to figure it out, so if you have any questions, PM me
