Hello Carl,
Thanks for taking a look! Sorry about the raw code, figured maybe it was something I was doing outside of just the SWFLoader/Greensock. Here is a simplified version that I created to try and match the setup of my actual project. It doesn't throw any errors as my other code does but doesn't seem to Load/Unload any of the content into the contentHolder in Main. Hope this helps better demonstrate my setup without all the clutter.
I didn't include com.greensock for file size, but I have it stored in the root directory...
sample->com->greensock->* in my sample project and actual project.
Also, not too sure the best way to share files through the forums as of now, but here is a Fast-Files link to the Sample.Fla.
Sample.Fla
*Edit*
I just realized Fast-Files is kind of shady when looking for the actual download of the file, there is a subtle and small 'Download Now' button below the horizontal ad-bar, sorry for the shady file link.
