So, when I try to Export an animation as SWF or MOV, it doesn't happen. I can't preview the animation as well. Usually, this happens after I draw something. When I open a new file, I can export and preview, but later I just can't. What shows when I try to Preview or Export is one split second of the green loading screen tha normally appears. I hope someone understand what I'm saying, cause English is not my nativa language.
I've noticed that the problem happens just after I save and close the file. I can export and preview until I save and close the program, when I open the file, I'm not able to do that things
Check where you are publishing the SWF to. It may be in a deeply buried folder, or on a network drive. Before you do the save the SWF is made into a temp folder, which may not have the same path problems.
