Project 64

Okay, so I got project 64, about a week ago and now I need it on another computer, so I put the set up with the games on my Ipod,(since i currently have no acess to my flash drive) and installed on my older computer which is goin' to my sister, but It says the plug-ins are missing, or invalid. So I go back and transport the plug-in's to my Ipod and try to replace em' well the thing is, when i open the plug-in's folder their all there so i think oh so they must be invalid or something. Well these outta word so I replace those withe the ones from My Ipod and it still dosen't work. the Emulator works fine on my newer computer, so I know all the plug-ins should be good. What's goin' on?
