Last year I made a Flash presentation and I need to edit it. I can't find the version saved on the Vista machine that made it, but I have backups saved on a Mac. When I try to open the Fla files, it says "Unexpected File Format".
I haven't upgraded the Flash Version since I made this (CS3). I've tried removing the extension on the mac and adding it back on on the PC and zipping it and unzipping it. (These are two solutions I've found for this problem.)
Does anyone have any other ideas?
