Hey, so I made a Tekkit server my friends and I can join to play around on, but the problem is that I appear to be missing some mods. I just recently (about 30 mins ago) had to update my Tekkit when I started it, but I don't know if that's the problem. It appears as though my server has an older version of the mods that I have. It says that I am missing so and so mods, and I need them to join. Upon closer inspection I realised the ones on the server are outdated.
Any help?
