Thank you Mylenium but I've already read the article. But it only occurred after the 14.1.1 update and CS 5 gives no warning.
Could there be a way to reinstall the Media Server?
(Strange to reply to my own message but there is no "Edit" button)
For what it is worth: I restored my Windows to a previous state and everything worked fine again.
Off course CC wanted to update my PS and Bridge and I let it do so. Now everything still works fine but the PS "About" screen states that I have version 14.1.
Guess the only thing I can do is wait for 14.1.2 or so...
What pervious state? can you explain a little bit? because I got the same problem and I cant solve it, I would be grateful if you could explain a little bit thanks.
