With that version of forge (and disabling tfcwatercomp) the server starts.
Here is a portion of the log of the previous error just as reference: http://pastebin.com/SvE1cXDF
But I think the problem was a script from other server. Since there is no "Download server" option in the launcher, I used the Technofirma server and moved the mods/configs, but I think the scripts folder was "merged" instead of just replacing it.
Which version of the pack are you using? I am seeing messages from mods that I have recently removed.
The Recommended version is pretty old and still buggy, but it has the most complete questbook. It is possible that the server download for that version is no longer available
The most recent versions are very broken, with lots of orphaned recipes and an incomplete questbook, They are really ment for testing in a creative world. However I think FTB may only provide the most recent server version for download, but I cant be certain if this is the case.
