GTA San Andreas won't load, any advice?

well for some reason i started up my computer and double clicked the san andreas icon and then nothing loads up, at first i see the little hour glass thing for a bit then it goes away. i don't know why it doesn't work because yesterday it was working fine. my brother said it might have to do with the link or something but anyone else got any advice? when i double click it, i see the program on the Process list in my windows task manager but like a second later it disappears just to let you know
