reading the manual was the first thing I did, but I am a bear of lttle brain.
After doing this:
"If you have found a sound you like and want to write it to the pedal, click on theWRITE ONE button in the top left of the editor screen. Locate the program file. If thefile name begins with a two-digit numerical prefix then this is the location (slot) on thepedal to which it will be written. If you want to write it to a different slot, first renamethe file, prefixing the name with the two-digit slot number of your choice. When youare ready to write the program to your pedal, either double click the file or click Open"
i have a dialogue box stating "FI not present or a communication error has occurred!".
