Found the conflict guys, It was just sir. Sengin being a jerk and purposefully making his mods incompatable so that tekkit can't use them. That, and there was an extreme conflict in the config files file. For some reason forge had generated twice as many config files for each mod as it was supposed to creating id conflicts all around without realizing it, so it didn't show up in the crash log.
Unfortunately that is not the case. These mods have been working together smoothly for about a week now with absolutely no conflicts whatsoever and I'm still getting the error message.
