Wow vinyl-junkie, it is working now. Thank you so much for your great support.
I don't know how the line breaks entered the udm-custom.ini file. The problem was really difficult to see, since I was always under the impression that the line breaks are from the display in the editor rather than being actual line breaks.
Thank you very much!!! I owe you something. How about a dinner invitiation when I am visiting Seattle (not sure if this is still going to happen this year though).
