Whats the error???

>I have a very simple program that copies some files from a CD to the hard drive. I have compiled it into a EXE and I am getting an error with the message being: DO D:\mydir\myexe.exe. I only get the error when I try to run the EXE on the CD. If I copy it to the C: drive then it works. I added a CONFIG.FPW with a RESOURCE = OFF and I still get the error. Any ideas? TIA!
