+

+
+- yellow warning indicators under **Process data**;
+- yellow warning indicators under **Frames**.

+
+## Resolution steps
+
+Follow these steps:
+
+1. Connect an external monitor to the robot controller.
+2. Restart the controller.
+3. Sign in with the following credentials:
+    - Username: `KukaUser`
+    - Password: `68kuka1secpw59`
+
+    !!! warning "Keyboard layout"
+        The controller uses the German keyboard layout (`DE`) by default. Take this into account when entering the password.
+
+4. Copy the complete project to a USB drive.
+5. Open File Explorer with ++win+e++.
+6. Go to:
+
+    ```
+    C:\KRC\Projects
+    ```
+
+7. Replace all files in this directory with the versions from the USB drive.
+8. Run the system restart application from the controller desktop.
