| Steps | Cause | Resolution |
| 1 | The graphical interface can be blocked for several reasons such as the simultaneous process execution specific to the dedicated computer. | Please press the ALT + F4 keys simultaneously. If this does not solve the problem, please restart your dedicated computer by pressing and holding the Power button until it stops. |
| 2 | After rebooting, the interface of the dedicated computer still does not respond. | If this does not work, please contact AMA Customer Support. The article available here explains the procedure to follow. |
