Access FAT created text file from Adobe Flash GUI

Using an RCM4000, I am having trouble accessing a FAT created text file, from my Flash GUI. When I #ximport a sample file, the GUI works fine, but when I alter the file with the FAT code, the GUI doesn’t read the new file. I can read the fat created file via the UNIX.c sample, so I know it’s in the rabbit. Maybe an easy way out is to change the file that the #ximport 'ed symbol is pointing to?
