Is this a modpack without any added mods? If not then this error is the way RedPower says it has an ID conflict. Check out this thread posts 4 - 7.
If this is a modpack without any added mods then check your install path for the words tekkit or technic. If either of those are present you need to reinstall FTB following this guide exactly.

tried it on an other pc (not capable of hosting it) and it worked just fine
edit: map witha similair name caused prob (i think) renamed it and it worked fine
