Hi Since updating to Mavericks I'm having huge problems with Illustrator CS5 amongst other things. The first problem I experienced was that Illustrator eps's wouldn't open - an error message of "Can't open or print this file" kept occurring. I've researched on the Internet to see if there are currently any fixes. One mentioned was to reload Java, which I did before restarting. This fixed the problem temporarily & I happily got back on with my work. But an hour later I started getting the same error messages when trying to open previously created files. Reloaded Java & restarted again, just in case, but now my Suitcase Fusion is not working either! Does anyone have any ideas on how to get round this? Seriously regretting updating my OS now.
