When i Launch my minecraft, i get a molten Redstone error about id conflict w/ Thermal expantion. would you mind if you add compatibility with Thermal expantion? thank you

There is some compatibility with thermal expansion, see http://projectredwiki.com/wiki/Compatability#Thermal_Expansion
I think you need to change the id's in project red config file to fix

i dont know a lot, but configs are generated by your client when first starting a pack, so i assume you added one of those mods in after the other already had its config generated, as long as you didnt change much in your configs (of worth), you should just be able to delete the config folder and let it regen with your current modset

Just change the configs...
