well, i was having a very hard time with keeping the game running and always having the program stop responding. I had free system resources during these events, the only thing i noticed was that the hard drive was reading constantly. So i went and tried changing the .exe files to run as admin (they already were), defragging, everything. The thing that actually did fix it for me was that in my file manager i went to the directory that contained the star wars directory, and noticed it was highlighted blue. upon right clicking and checking advanced properties, i noted a checkmark that said compress to save disk space. i unchecked it, let it process it for about 10 minutes (applied to all sub folders and files), defragged, and since then i havnt had a problem. I dont know if this is everyones problem, but it worked for me, sometimes the game would even become unplayable. No issues now.
Good luck!
