also the achievements still aren't working for me, is there a way i can get them to work?

The way to 'unlock' them is to travel to the easy and medium islands to get to the hard ones. You dont unlock them, its just you have to travel down the other ones first

thats basicly unlocking them
and i know thats how you unlock them i want to know which island i have to travel to in order to unlock them

Easy dirty travelling guide: go up when you can, if you can't, go right.

For a more advance explanation, see http://steamcommunity.com/app/440650/discussions/1/1470841715944020635/ (it does include the old island group, but the travel system is the same)
