Rated 4 out of 5 stars

It's a great add-on, but an error prevents you from adding more activities like Google Define, Google Maps, etc. The error always says:
------------------------------
The activity provider could not be installed.

This might have happened because:
- A required file could not be downloaded
- The website is unavailable
- You are not connected to the Internet

You might want to try again later.
------------------------------
I'd suggest fixing this in a future update if possible.

This review is for a previous version of the add-on (0.7.6).
