I bought an online copy of Solidworks. After installation I tried activating theS W. I keep getting the message shown below, however this is the first time I installed SolidWorks so I have not activated the product on other computers. Why do I get this message and how can I succesfully activate? 

I contacted Solidworks support a few days ago, however still no reply.

Can somebody shed some light on this?

Looking forward to replies.
