Problem with Iteaduino Tiny and Digispark programmer

Hi!

I buy several months ago a Iteaduino Tiny http://imall.iteadstudio.com/im130615003.html , i need now to use this board urgently !

I read the Wiki and download DigisparkArduino-Win32-1.0.4-May19 folder.
I install with success the DigisparkWindowsDriver (Windows Seven 64Bits)
I use the arduino program into Digispark-Arduino-1.0.4 folder.

I program avr to DigiSpark(Tiny Core) at COM16 and DigisPark programmer.

I try to upload a exemple sketch and the avr ask to plug the board.
I plug Iteaduino Tiny, green led is on and red led is blink.

I obtain every time this type of error :
