This appears to be an invalid license key for?

Trying to get our key to activate on our site to update the theme but we are getting the following message “This appears to be an invalid license key for”.

I have tried deleting the key, saving and then re-entering the key as suggested on other posts but this makes no difference.

Site is www.nevadaconstruction.co.uk

How can we get this to work?

Anyone able to help?

Hello there,

Probably you would need to upgrade your license first only if you run Sydney Pro older than version 2.
