I can try...but no guarantees that it's something I can fix, since I'm not at all familiar with ProfitUI.
I can't think of anything in my mod that would possibly conflict...all the information and data I used is found in the default XP bar file, IIRC; I just rearranged it.
Where are the C2C buttons located that you're trying to use?
Just to make extra super-duper sure, you CAN use C2C when not using my XP bars, right?
