Magic Sheet Images not Saving to Show File

I don't know what's going on, but here's what I'm getting:

When I import the images into your show file, the file is not saved properly. The show is saved but not the images.

When I import your images into my main showfile, the file is saved properly and everything is fine.

So is there something wrong with your show file? Maybe try again with a new clean file/setup.

Another thing I noticed is that your show file is only 162KB. For me a new empty file has a size of ~7.6MB

a new empty showfile should be something like 25kB...

You are right. I forgot to remove my A3D models.

Thank you! I originally created this in 3.1 but was opening it in 3.2. I upgraded my offline to 3.2, opened the original file, resaved it and now its working fine across other devices. Thanks for helping me figure that out. I still think it would be great if ETC provided better literature on how this is intended to work though!
