I'm working on an AIR project at work that has around 100 icons saved as FXG files. They were all originally made using Illustrator CS4 and unfortunately whoever made them originally never decided to save the original .ai files, they only exported the FXG files. Now all we have is the CS5 suite and whenever we try to open the files in Illustrator CS5 to make edits we get the error: "This FXG is invalid, validate it before opening".
We have one guy overseas who still has a copy of Illustrator CS4 and says he can open the files. Any ideas on why they would be coming up as invalid in CS5? Could it have something to do with CS4 using the FXG1.0 format and CS5 using 2.0 and there's a lack of backwards compatibility? I've never worked with these kind of files before so any help would be appreciated!
