Ok, i might as well be honest to get the answer i need, hope someone can help!! Im going from a cracked version of reason 4 to a legit copy. Problem is, i have no idea how to delete the license off my mac. I have tried completely uninstalling reason and ive been through the library into app support and the receipts folder and deleted anything reason related, but it still stores the cracked key?!? How do a delete my license key so i can use my legit key? Can anyone help? I dont know where else to look!
