Sketchup Pro 2015 Activation - Sorry :(

Treading a path that it seems several others have done before me.

Have a laptop running Sketchup Pro 2015 and have just replaced it with a shiny new Ultra 7 but 2015 won’t activate, clicking on the activate button does nothing.

I understand there’s an issue with the activation server and that there may be a workaround.

Could anybody help?

Many thanks!

@colin might. Or at least he might know why it’s not working and if there is any other solution
