Loading HSO into Cubase 10.5

Recently purchased Cubase 10.5 and already had the original Halion Symphonic Orchestra DVD’s and license I purchased in 2006. Trying to load HSO but it keeps stopping with a warning stating other activated processes on the e-licenser are preventing it being loaded. Is there a fix? Thanks!

Hi and welcome,
