Storyline Memory Issues?

Hi, has anyone run into issues with low memory while running Storyline? I ran into this yesterday for the first time. I'm using a company-issued laptop, which is pretty robust - 4.00 GB of RAM. While working on a .story file, I got a "low memory" warning - I tried to save my .story file, but got an Articulate message "Failed to save 2 items in array." (or something like that). I didn't have a lot of other stuff open - just Outlook and a couple Word files. I will also talk to my company's tech support team to see if there's an issue with my computer. Thanks!
