thanks again, yet please consider that it's not easy to remember, every time a part of hardware is being changed, what has to be done to mantain efficient every addon installation
my opinion is that I slightly prefer, with smallest addons, the uninstall/reinstall way (deactivation included), more intuitive about the solution to take
in my case, four examples of different behaviour (so far experienced, .... always better than reinstalling a 400GbFSX):
LevelD767 blocked FSX and told me that I had to reinstall from scratch
ActiveSky2012 reactivated all by itself
EZCamera, needed its folder to be deleted and to reload over from wrapper, to mantain customization
XPOI had its own way, with server troubleshooting
if then we consider all businesses of life ... we might suffer from shortage of personal RAM
