App Store problem in Yosemite

Hello,

I downloaded Yosemite on my MacBook Air and iMac (not the 5K !) from the latest edition.

When it's done, I've got a BIG problem. My App Store in completely not working ! It doesn't recognize my bought apps, it doesn't show anything on updates, only a grey screen... and images are missing in applications presentation : the logo is here but the big image on the right of the image doesn't show up. I can't receive any notification from the App Store. I was very angry and tried to lunch the App Store via Terminal. Here are the results :
