Low on Memory?! Cant save!

Yes, I'm still having memory problems that preclude saving a project file in Storyline. I have a project that ideally would include 46 or more scenes. I've had to break the project into three projects. Each scene is composed of approximately 10-12 slides. If I get in the 15-16 scene range, I have no guarantee that the project will save after making corrections/changes/additions. I have routinely published the project (someone told me once that that would reduce the size of the file and reduce the chances of it not saving). I have the latest version of Storyline installed (Update 4) and am running on a i7-2600 3.4 GHz system with 8 GB of RAM. I wish it were not the case, but the issues have not disappeared with Update 4.
