Delete the C:\ProgramData\ideCAD10 folder.
If you can't see the ProgramData folder, it may be in a hidden location. You can make it visible by checking the "Show hidden files, folders and drives" option in the "Advanced settings" section.
Hold down the Ctrl + Shift key on the left of the keyboard and run ideCAD from the desktop shortcut.
Keep pressing the Ctrl + Shift keys until you see a message saying "Registry entry and settings are cleared" .
The message may remain in the background. Observe the message that appears.
Click the OK button to close the dialog. When the program opens, load your project and try again.
With this process, the menu, toolbar and shortcuts are made into ideCAD's initial state.
