I created a ُSWF file with the Swish max 4. Then I loaded it in Captivate Software. But I got a message saying that "The Adobe Flash file "Test.swf" contains ActionScript 2 while the current project setting is ActionScript 3. This might cause the Adobe Captivate project to work incorrectly or stop working". After that animations are not fully loaded. How should I fix it?

Action-script 2 and Action-script 3 are written differently, there isn't a converter as far as I know. You would have to rewrite the code. Or you can change the project settings to Action-script 2 if you do not need Action-script 3 capabilities.
