I need to get rid of paint stain on my Jacket?

I was at school and people were painting the walls. My jacket got on it (the sleeve) and it's still on it. I was scrubbing it off with soap and tide to go but it won't go away. My jacket is white and brown paint got on it :( My jacket's made out of 79% cotton and 21% Acrylic. I got it from gap and it's 40$!! ahhhhhh!!!!!! I scrubbed reeaaal hard... Any natural formulas? or anything I can find at home??? HELP!!!!!
