We are still having save file issues. Illustrator will not save the file over a network or even at time to the desktop. Also please do say "this is not a generic issue" looking at all the posts below with the same problem it surely is.
And please can we get moving on this. There seems a real lack of effort to fix these things. Whenever I read these posts you guys are always saying you have fixed the problem but the posts show that you have not, or you made the error occur again in another update. Very disappointed with the tech support effort and Adobe.

Same problem. Illustrator sometimes saves, sometimes doesn't. And if it does, it won't let me open the saved file. It says it is locked or in use, when it is not.
It also won't let me save as a PDF.
