Animate help please!

I'm trying to animate a picture I made for school and I can play it fine on the main screen but if I go to test, nothing shows up and it tells me to load flash and then I get a screen saying adobe no longer uses flash. I try to export my GIF and my preview is not going my animation at all, just a blue screen. What the heck is going on?! I know animate was recently updated. It was working fine before that. I don't understand why it is not working now. I used action script. Does this mean Animate no longer supports making animations? That doesn't make any sense. Why is it not working? Anyone else having the same issue?
