Problem With Serial Slave Uploader

Hey, i downloaded many different versions of the Serial Slave Uploader...but they all have the same problem...I read somewhere that the sides of the screen are supposed to turn blue, but mine just freezes after it sez "SEGA produced by or under license from Sega Enterprises" I have tried the one that XENA gives, but the same thing happens.... What am i doing wrong? I downloaded the file and used Diskjuggler to burn it, now wat?
