Alright so, when I check to see if I have enough RAM in my computer it says I have 3.48 gigs useable so I added about 2000 megabytes of stuff to the SWTOR Unleashed thing but when I go to run the game I get an error that says this "You lack 414MB of RAM free to put SWTOR (2.5gigs) and unleashed RAMdrive (1.0gig) in RAM. That is without even taking Windows required RAM! Try to free up RAM or put less things in the RAM."

Now, I'm not very computer savvy at all so maybe I did something wrong but is there something I can do to move some things around or delete some things?
Or is it not possible with only 4 gigs of RAM?
