Dear Sir,
Following are reasons due to which this message is shown:

2. On same server multiple LAN adapters are present and activation is done with one of the adapter and you are trying Activation with different adapters.
Please try following steps:
- In case from above reasons, point no. 1 is applicable
Request must be sent to MKCL team with appropriate reasons. After scrutiny and confirmation necessary steps will be communicated to you.

Disable all the other adapters present on your machine and use the adapter which is used for activation earlier.
You can disable adapters from Control Panel -> Network and Internet -> Network Connections.
