Hi! I've just accessed the trial version of Cartoon Animator 4 to see whether it will work for me. Found a free tutorial on Udemy (2D Animation 101 Courses) and following it on importing and opening up a template PSD file. I found out I can't seem to drag+copy the layers on one PSD file unto another open blank PSD file that I have. I'm not sure what is the issue... but I have a hunch. Do I have a very old version of Photoshop that is not compatible with CA4? I'm using Adobe Photoshop CS 5.1 Extended. Is there a workaround? If not, may I know the oldest version (not yet CC) of Adobe Photoshop that CA4 is compatible with?

EDIT: I think I just realized the problem. The version of Photoshop I'm using does not have the functionality yet to copy-paste Folder Layers from one PSD file unto another. :-P I hope modifications I make in the PSD file will still carry over automatically to CA4 though... Will post update later on.
