Autosave

Storyline 3 has an auto recovery setting, but does not have a auto save function?  Many times I try to save my project, but the screen keeps saying that I have to "Save as" because another program is running.  I don't know why that is. The project is the only one that is opened. Then it saves the file several times on my computer. This time, it didn't save anything even though I tried to save twice. Does anyone else experience that?
