It looks like I need to explain more thoroughly.
I made a "config pack" that contains configuration files for the mods FTB uses. It has no actual mods in it. This means that whilst you have the settings for the mods in the pack, the actual mods themselves need to be downloaded separately and added to the pack manually.
The idea is that you copy these new config files over the ones in your existing pack and this quickly and easily (or as easy as it gets right now) allows you to change the settings for your modpack to whatever the new configs set them to. The pack was originally made because an "easy mode" for GregTech was the most commonly requested feature for FTB at the time and I responded to that need personally after having basically done this on my own anyway for personal use. There isn't actually an Easy Mode for GregTech so what I had to do was heavily modify the config file to make the mod easier to play. When you copy this changed config over the original one and load the modpack it will run on the changed settings from then on unless you update the modpack or otherwise reinstall it, as FTB downloads fresh config files as part of the modpack download whether you want it to or not.
Also, I made a config pack because making a modpack is where all the permission ragewars come into it and I'd rather not waste my effort on that. Besides, the config pack is basically Ultimate+ anyway.
These days the config pack is a modified version of Ultimate's configs: it's designed to work with Ultimate worlds but will work with other modpacks perfectly fine as well if that's what you prefer to use. I have added additional support to this config pack for the mods in the Ampz and DivineRPG packs. These are unofficial config patches that allow these mods to work in FTB worlds without breaking anything from FTB. Unless DivineRPG is actually added to an FTB pack officially, this is the simplest way to get DivineRPG working with FTB. Once you have installed the new configs, add DivineRPG to your FTB pack of choice and it should work fine.
The config file I use for DivineRPG changes
absolutely every setting. This is necessary to get it working with FTB. This also means that existing worlds from the standlone DivineRPG pack won't work and there's nothing I can do about that unfortunately.

This is also why people have such a hard time adding DivineRPG to FTB packs - the default config treads on the toes of pretty much every other major mod in the pack!
So far other than Sephrik's offering this is the only way to get DivineRPG to work with FTB without manually editing the config file yourself. Give it a shot and see for yourself, the link is in my sig. Back up your world before making the changes just in case.
