First: I looked into my config folder and found two JARs. But if it works with your BareBonesPack all is right, so that can't be the Problem. But, I can't find the log from Forge. I don't know if I'm too dumb or something is really going wrong...I think for normal they're in the modpack directory (.technicmodpacksmodpackname). But there, I can just find "options.txt", "output-client.log" & "output-serer.log". I searched in all Folders (bin, cache, config, coremods, etc.) but I couldn't find that log file...
