that player its me, i just cleared the cache but nothing changed.

hey you solved the problem, when i opened the first link i read that i had to change the date of my computer, cos i don't know why every time i turn of the pc the date come back to the 22 december -.- so the problem was just the date, but now i don't know why time and date come back all the time XD hehehe&nbsp; thanks anyway !!!!
