Like others, I’ve had big problems with the new update, it vanished from the menu, my reinstall didn’t work, I bought GSX again, that didn’t work either with my mapped key ingnored, duplicate GSX entries and complete software crash during pushback.
I have kept my original purchase file, and all the updates of GSX and had installed them in order as I had received them from Viruali, It didn’t work and it asked for an updated AddOn Manager. That only caused more problems.
And so I deleted everything and simply installed the last big update I possess from December 2016. It works perfectly in every way, though I do miss some of those national accents!
So, rolling back is doable … but I had to roll back further than I would have liked.
