I bought Virtual villagers in the past and have used the games without problems. Now I've tried opening my old games on my iMac which now runs version 10.9.2 and they only crash. I bought a new Virtual villager 3 last and it works but crashes when I try full screen 27". Is there a way to sort this out please?

Yes there is! I merged your two posts into one, so that we can keep things in one spot on the forums.

I do see a few purchases for you, but we will need to ask for and provide some some personal information, so if you don't mind, I'd like you to go ahead and fill out a Support Request. In the message section, please say you are Kio on the forums, list the games that you purchased, and I'll be happy to help you get those games working properly!
