• Open the ETABS Key Server application (or CSI_License_Server).
• Check if the service status says "Started." If it says "Stopped," click Start.
• If it refuses to start, check if your Firewall is blocking the port (usually port 5093 or 1947).

Change Regional Settings: Go to your PC settings and set the date/number format to United States (mm/dd/yyyy). This is a common fix for CSI software.
