I have posted a file on the web site at http://www.pcstitch.com/files/DLE.COL that is the floss file for DMC Light Effects floss. I will add it to the next update, but in the mean time, you can just download it and save it to the Flosses folder underneath your PCStitch 7 or PCStitch Pro folder under Program Files.
Thanks Mark! I got it for both Standard and Pro. It sorts funny though. The 4 digit numbers sort with the 3 digit ones. The 3000 ranges sort at the end of the 300s, and "E5200" sorts between the 400s and 600s. It's probably sorting as text because of the leading "E".
