Muiltiple layers wont show


I am fairly new to ToonBoom and I have been using it for a few months on Mac
Recently I have transferred the files from OS to Windows and things were working well until I open the program. When I opened the file, there were two primary errors.

First being that I cannot view multiple layers at once as the image shows

And second (probably related to the first) is that I cannot play the animation

When I transfer the files to a Mac, the files work fine

If there is anything I can do please let me know

My laptop is a Windows 10 with an Intel(R) Core™ i5-6198DU CPU 2.30GHz 2.40GHz

Thats hard to know.

If it’s related to mac vs Windows or the setup of your windows laptop.

If you dont get a good answer I recommend that you send a message to TB support.
The often answer fast.

I hope you get it solved.

I do not have a Support plan (Bronze, Silver, Gold), nor do I know know my activation key.
Are you sure they will respond?

I think they will.

Could the issue be about memory?

Often problems like this could be related to the graphic card. Have you tried to update to latest driver?
