That's weird well if you want to wait a bit longer what I would suggest doing (which is what I do to get my games from my laptop to my PS3 , with no issues also) is getting filezilla, and ftp (go into multiMAN and get your ip address, then go into filezilla and where it say's host type in the ip address, on the left side (your pc) go to where the game folder is, on the right side (your ps3) go into the GAMEZ folder directory like if you would with mmOS, and drag and drop the game folder on the left to the one on that right while multiMAN is still open, and wait while it upload's.) It take's a while but It's worth the wait because it uploads the game just fine!

Just run the game from multiMAN like normal assuming the file's are good of course. Let me know if you need any help!
