Sorry that my first post has to be a (possibly) simple question, but I am pretty stuck having never come across this before. I've been given an eps file from a client which looks to have been created in Illustrator (not sure which version but no more recent than CS1). When I open the file in Illustrator CS1 and CS2 the file is completely locked. The cursor icon turns into a pencil with a black line through it. Can someone please tell me how to unlock this file, or if it's not possible, and just for future reference, how to lock a file in this manner?!?
Many thanks
