Hi there Scott
It's a pity I missed your original post, I might have been able to save you going through the re-install
If I remember correctly, all you need to do if you get the "Can't Read or Write Data" message when loading the VS-20 Editor is to reassign the VS-20 as your MIDI device and make sure the input and output are both set to
VS-20 Effect Control - this will allow you to use the VS-20 in standalone mode and as a controller for Guitar Tracks.
To perform this, just click on the
Setup button on the menu bar to open the MIDI Device options pane - use the drop-down arrows to select
VS-20 Effect Control in both the Input and the Output fields.
Here's an animation I put together for someone else a while back who was having the same problem:
Hope that helps should you get the problem again.
And do I win an Oscar
Steve
