Any help?

!Warning! It is going to be much easier to use an updated version of minecraft to base your pack off of. At this point in time Mystcraft was still a jar mod, and not fully forge.

Now onto the help: Did you install it into the server jar file? I am pretty sure that this is caused by Mystcraft not fully being a forge mod in this version.
