The server has hosted a Tekkit Classic server recently, and that one worked well. So I can't really understand what's wrong with this one.
When I start it, it loads the mods, and then when it starts creating the world, I get lots of errors like this one:
2013-02-12 18:00:56 [WARNING] [TreeCapitator] Block ID <Forestry.log3> could not be parsed as an integer. Ignoring entry.
It then stops at: 2013-02-12 18:00:57 [iNFO] [sTDOUT] Loading NEI
Full paste of the failure is here: http://pastebin.com/kxuYw5UB
