Ok, sounds like you made a copy of the default folder (DefBrain). Did you rename it (the folder) to DENISE DAVIS or something? Within that folder, THAT DefBrain FILE, did you rename that DefBrain to DENISE DAVIS too? Assuming you have...
Then open that brain file and do what I said above - Change the 2nd and 4th lines described above. In your case, Name=DENISE DAVIS and DataFolder=DENISE DAVIS
Everything should work... if not then I really blew it and have no idea what is wrong in your case...
