is there a way to buy a product from the buddy store and just download it, not stream

I have 2 legit keys from the buddy store, but i bought a black market key from a shady character.



so i wanted to buy the tramper plugin, but since im just allowed to stream products, i can't use the black market keys with the plugin right?



Is there a way just to download the plugin from the guy personally and use that? or am i basically stuck with dead keys
