OpenRoads Designer - I accidently blew away my icons

I did a dumb thing. While tinkering around to setup OpenRoads Designer the way I want, I used the Customize Toolbar dialog to import an XML file that I exported from Microstation SS4. Ever since then, I get a huge list of Unable to load/create dialog item of type 'IconCmd' errors and several very important tools are missing from the modify toolbar.

I've tried the following with no effect:

- Uninstall / reinstall OpenRoads Designer

- Run OpenRoads Designer with "-restoredefaults" added to the shortcut command

- Deleted the files in my c:\Users\....\AppData\Local\Bentley\OpenRoadsDesigner directory.

How do I undo this and get OpenRoads back to normal?
