rapid share is notorious for having small upload space so most peole who use it tend to rip their games down. and if they dont know what they are doing then you are the one who suffers.
i shy away from rs as much as possible cause of that and the cool down time it takes to be able to upload. next time try looking for a megaupload or giga size .
if you do mega upload you can change your ip and trick it to let you dl.
here is the link to do that.
