Bought 2 loop sets from Steinburg works in ver. 12 but not in 10.5

Just bought the country violin and the thing sound sets from Steinburg and cubase ver 12 recognizes both while ver 10.5 recognizes neither. Everything is set up correctly. The only thing that makes sense to me is 10.5 is not allowed to use them. Thanks for any help

Hi @billcarbonia and welcome to the community! These loop sets use our new licensing system and only work with Cubase/Nuendo 12 and 13, as stated in the system requirements.
Cubase 10.5 uses the old eLicenser-based licensing system and cannot recognize these new licenses.
