Hi! I can clarify most of these points here and give some advice.
It shouldn't have removed your friends, the update preserved my friends, so you should fill out a support ticket for that. That's very strange.
Free play tokens! This is either SMG trying to push people into getting premium, or it's a bug - I'm inclined to the latter. I've filled out a ticket myself about this. However, it's very very strange that you only get one token from advertisements, I get 5 for each.
I will give you a piece of advice here as well: I know it shouldn't need to be something to do, but you can always create more Risk accounts, which will each have separate token amounts that you can then use to play more games each day.
Update: Here is SMG's statement on the token issue. "We had a mix-up in our token economy database when updating the servers
for the 2.6 version of RISK. Please restart your app, all original
values for coins per game have been restored and we are looking into the
other values right now."
