ETABS Analysis Error

[bwavering]

Whenever I go to run my analysis, it begins to run the analysis but then stops and says it was incomplete. It tells me that there is a File run error #3. Ive done some research on this error but can't get anything to work. Directly above this error it tells me that there is no (unrestrained) mass in the structure. Well I'm researched this too and it tells me to set all my mass and weight modifiers for my section properties. Ive checked this over and over. My material properties even have weight and mass assigned to them. I can't find one reason why the damn thing isn't running. I have attached a screenshot of the analysis errors (Sorry can only attach one file). I have also attached my stabs file to see if it might possibly work fine on another computer and its just mine.

Thanks for any help you can provide me because this is for my masters project which is due in a few days!

Im also using version 9.7.4
