Essentially, I don't know how to change the plugins I bought from trial version to the full versions. I bought the Signature Bundle and a few of the plugins/VST changed from their trial versions to the actual full version ...
64bit version of FL-Studio so this is a problem.
I don't think the midi controller is the problem since ITEM menu wont work on any 64 bit versions from 10,11,11.1 up to the latest beta 11.5.13 ...
