Ahh... well at least that gave me a direction to go. Selecting different views didn't help, neither did re-installing over the top. What I did do which at least stopped the error popup was stopped the program, went to the PresetViews directory and noticed the Last.preset.dock file was timestamped about the time the issue started happening for me. I renamed it to Last.preset.dock.old and restarted the program. Viola! Error no longer comes up.
