Thank you for the question.
Your subscription has expired on Dec 18, 2016; so you can install any version of PHP Tools released up until this date (it would be the version
1.21.9350 from our Download page). You can reinstall Visual Studio and activate using your license key, there won't be any issues with that.
Sadly the subscription can't be renewed since it's more than 90 days since the expiration. If you'd like to update to the newest PHP Tools version, a new license has to be purchased. Please contact us by email in case you'd be interested in a loyalty discount, or if you'd need additional help.
