Hi Douglas,
What is the error message you're getting?

I noticed another similar question on the list a few days back, but I don't
think they've gotten an answer yet either. I've worked with CTF data in
EEGLAB before so I can try to take a look for you, but I'm traveling right
now and it's going to be a few more days before I have access to my CTF
files to play with.
