Sorry, access denied - Solidworks 3d Experience

I'm looking for some help, as for some reason when try to log in to the 3D experience platform I get the below message - 'Sorry, access denied. You don't have access to this 3D Experience platform.'

It was working the other night, I'm still within my subscription period and there seems to be no way around it. 

Very frustrating, especially as there is no direct email address where such questions can be sent - or if there is, it is not well advertised.

Any assistance would be appreciated.

Kind regards,

Mike
