I created a Flash Animation for a school project in Adobe Flash CS6 at home, and at school which uses Adobe Flash CS5, I can't open the flash file. Is there anyway I can make this happen, because until then I can't work on my project.
You will need to save the file as a CS5 file if you want to open it in CS5. I do not know if CS6 saves for CS5 but it is likely that it does since Flash normally allows saving one full version back. Choose Save As when you go to save it and select CS5 as the file type/version.
