How do you make a working copy of the ps-x-change2 cd?

[licorice]

Hi all,

I purchased a copy of the PS-X-Change 2 CD and for the past month it has worked fine as I'm able to play most of my backup copies of my psx games.
Now, I've tried making a backup copy of the Change cd itself but the psx console does not recognize it. Let me point out that I've used clonecd, cdrwin, discjuggler, and blindwrite without success. How do I make a working backup? Does a patch exist? Must I modify the tracks? Thank you.
