After the latest update was installed, when I went into the drop down and tried tp open the surfacing wizard it froze my computer. I tried several times after that and got the same result. I uninstalled the Control app and downloaded a fresh install but again i cannot open the surface/flattening wizard oh and worked perfectly before .
Please delete the lastSurfacingTool setting as described here: Control 1.0.350 Wizard & Tools crash Then try again.
