I installed my CV1 last night for the first time and used the tutorials just fine.
I then downloaded two free games, and they open, and bring me to the first main screen. Then nothing happens. I can't actually start using them. All I get is the games "environment" and a white dot in the direction that I look.
The first game was some "Bear" experience and when it opens, I'm in a woods environment with a chalkboard type board in front of me and a triangle made of like popsicle sticks under it. Nothing written on the board. Never leaves this screen. Cant do anything. I waited like 5 minutes.
The second game was a "Combat Simulator" experience and when it opens, I'm in an Asian Village type environment, and there is a paragraph about what the game is and a "Watch Trailer" button and two girls on the left side. When I hit the trailer button the paragraph and girls disappear leaving me in the village and can't do anything. If I don't hit the trailed button, it leaves me in the same condition with the paragraph and girls and button still there. I waited like 5 minutes.
Please be way more specific as to what "two free games" you have tried, neither sound like anything I'm familiar with, and there could just be problems with these?
