With that phrase I want to say that before the update everything went well and after it I appreciated the problems.
Ok so, it went from "all is well" to "bad", not from "bad" to "worse". That's what I wanted to be sure of, it worked well before...
Exactly the problem is that when pressing CTR + F12 before leaving the menu to choose the options
I'm sorry, but you must try to make some effort to write more clearly, because this sentence is quite cryptic. What do you mean with "pressing CTRL+F12 before leaving the menu" ? You first press the GSX hotkey, THEN the menu come, and THEN you might eventually leaving it.
and now nothing comes out
Please clarify. First you say "before leaving the menu", now you say "nothing comes out", do you mean the menu you said you are going to leave, is in fact not even coming out ? Are you referring to the GSX menu ?
Try a "Restart and rebuild the airport cache" from the GSX menu.
