I have used Message+ successfully on several of my devices for years.
I just updated my Galaxy Tab to the latest version (2/4).
When I open it I get a message "Message+ requires additional permissions to run".
I click OK.
It goes to "Application Info" for the app.
Then nothing. 
What permissions do I need to enable?
Interesting software development here. Ignorant messages wouldn't pass UAT where I'm from.
My developers wouldn't release it to UAT with something like this.
Thanks for any information you can provide.
