Hi scorpio,
Please download the latest version of progeCAD and re-install *over* your current installation. DO NOT UNINSTALL FIRST:

A litlle bit more information might be needed to tell you exactly what happened. What operating system are you using? Did you change anything? Did you apply any updates? Do you see any changes with any other software? What kind of antivirus software are you running?
