routing help! using Eagle

i am just a beginner at electronics and eagle. i am having problems routing the AVR ISP. a few tracks are trapped and i just couldn't route it to its destination. i have tried for days to make it work, but it seems too complicated. the zip file below is the whole design with a Design Rule file (.dru). any tips, comments, etc would be appreciated =] or if you would like to route it, that'd be great. thanks.
