WHenever my friend tries to join the Official Server, he gets this message:

mod rejections[FML Mod:LOTR{Beta v28.2 for Minecraft 1.7.10}]

He has the right version installed and the proper forge version, so I don't know what to do. I try to help him figure stuff out, but it sometimes gets difficult because he uses a Mac, so yeah. DOes anyone have any suggestions? Please help!
