I just updated to CS5 because since 2004 I have made ALL my presentations in Flash and until CS5 I have not had any backward compatibility problems opening my presentations, but since I upgraded to CS5 I CAN'T access any of my old presentations! I have tried to search the web but can't find any text on this...
Attached to this message is the error message I get when I try to open my presentations (made in CS4 and even earlier version of Flash) in Flash CS5.
