Rigride

So I'm definitely not a computer expert but I downloaded the file and put it on my SD Card. Follow the steps and punch in the up,up,down,menu,left,right. It gives me an option 0=wince Upgrade so i select that. Then it has options 0=wince by SD/MMC (format) or 1=wince by SD/MMC. I've tried both and when I select them a red message pops up on bottom and says (Can't find WINCEIMG.CKS file!) Any key to continue. PLEASE HELP!
