I tried to install PE-DESIGN or remove PE-DESIGN again and again, but I failed it.
After uninstalling PE-DESING software, only the background image is displayed on the screen.
When trying to upgrade from an older version, the message "Cannot connect to the Internet." or "The server could not be connected to. Wait a while, and then try connecting again." appeared and "PEDESIGN Software Key" could not be upgraded.
