Okay, so I managed to get Hazel back! Here's how I did it.
In the Cortana search box type, "Settings"
Select, "Connected Device Settings"
Click the back arrow when the Settings window appears
Select, "Time & Language"
Select, "Region & Language"
Select the "+" where it says "Add a language"
Add "English (United Kingdom)" Language Pack
Then Select that language pack once it shows it is added
Now download it
Open up Voxcommando and enter the TTS plugin
If Hazel is already downloaded, it should appear in the TTS plugin
