the above response was 100% accurate- it worked! Thank you!
One thing to also be aware of is there is "Line 6 Central" that you can download that will allow you to update the software. I've been told that sometimes updating through POD Edit can get messed up.
If you are taking a big jump between firmware versions, consider doing it in steps. I went from 1.4 to 2.0, then to 2.5. It wouldn't work when I tried to go from 1.4 to 2.5.
Good luck all!
