i am in dfu mode (according to sytem profile) but SeasonPass does not detect


I am having a lot of trouble getting the SeasonPass to detect my apple tv 4.2.1 in dfu mode.

In a system profiler (apple 10.6.3) it says that i am in dfu mode, so i dont see what i am doing wrong.

Anyone an idea?

Love to start enjoying to software because since i have bought it in december i have never used it.

Thanks in advance,
