As you might have found out, we just migrated our site over the weekend (25th and 26th of January), so most likely you've hit site unavailability during the upgrade and migration. Please do the following steps:
- Uninstall the current extension from Tools -> Extensions and Updates.
- Close all instances of Visual Studio.
- Download the latest version from here and install it.
- Open Visual Studio again.
This should bring things back to normal. If you still have some issues or problems working with the extension, please, don't hesitate to contact us again.
Thank you for the understanding and please do sign up for our upcoming keynote
