I know I came late to your issue. Still, after 3 weeks of wrapping my head around and trying all sorts of things having the same issue (game wont start and aion icon disappear after 3 4 5 seconds once you start the game from GF launcher) it seems that I have found a solution which cut less and less the fails to start.
go to your gameforge folder (not game!!) -do this parameters for all this applications : gfservice,gfwebhelper,gfclient,gfhelper ; properties - compatibility - check: run as administrator, disable full screen optimization, run under windows 7 compatibility.
the improve rate of logins is significant high, so is safely to say that launcher have issues not aionclassic.bin itself.
you are all welcome
