It is asking to update my license key again and giving me an error for invalid email?

You will need to action the following steps:

Glossary: *The plugin you purchased at ExtensionWorks. Example this may be WooCommerce Commonwealth Bank.

Try deactivating the (*The plugin you purchased at ExtensionWorks) plugin entirely under

WordPress > Plugins

Reactivate the (*The plugin you purchased at ExtensionWorks) again and copy the ExtensionWorks Licence key.

Go to your website admin area   [This is YOUR business website: Go to Dashboard > ExtensionWorks Licences]

Paste the ExtensionWorks Licence key for the applicable product.

'Save Changes'

This action appears to become cached, if you encounter the problem again please provide WordPress login credentials and l will activate the key for you.

If you have any caching plugins activated it might be a good idea to flush/clear the cache.
