Nope that is not the question - perhpas I am not explaing it well. We are opening them and then saving them as CS6 with no problem but then the file becomes read only to any other artist that tries to open except to the artist that saved it as cs6. When it was CS5 everyone could read and write so I am trying to figure out how to make all files read and write once they are changed to C6. Thanks!
Sounds more like a server issue than anything else.
