Arduino TFT lcd problem

Hello, I bought Arduino TFT 1.77" lcd. I copied file to SD card and when I loaded TFTBitmapLogo four black and four white stripes displayed on LCD (I used Arduino 1.0.5). I updated IDE to 1.5.8 beta, and stipes are gone. But now, I have got another problem. SD card reader not works (before updating, it was the same problem). And I can't control backlight. It's always ON. TFTGraph sketch not works, too! :( Please, help me with this problem!

Sorry for my bad English, because I'm Polish.
