Storyline360 will not save because it says I don't have enough memory.

It won't let me save at all. As soon as I click on save it pops up with that message. I had to close it out with out saving. I restarted my computer. I stopped unnecessary programs from running and it still overruns with high memory resources.  I have never ever had so many problems with any other software. Storyline1 and Storyline2 were great.  Storyline3 and 360 have had so many glitchy problems.   My computer has 24GB of installed RAM. It's running an Intel Core i7 2.6GHz processor. Is that not enough?
