Storyline 3 Error: Available Memory is Low

This is the same issue I've got with Storyline3. Our systems are locked down though and I don't have admin rights over the folder I need to access to clear all the superfluous files that Storyline keeps creating.

I'm also having issues with screen recording in Storyline3 which I think is linked to the system memory issue. Sometimes the recordings work fine and play fine; other times they work fine, but then present a black screen when playing or freeze completely; and then they don't work at all and won't import back into the application. As most of the training I'm designing at the moment is for new IT systems I have to use screen recording all the time. It's getting almost impossible to use it now. I have raised numerous support calls with our internal IT department which initially fixed the issue, but as I can't delete those extra files myself it's becoming a nightmare task to manage. 

It's also causing Storyline3 to crash altogether and the only way to get out the system is to force a log off from the network.

Has anyone else had the same issues?
