Could you helps me on the following problem ?

I loaded -on Topfield 4000Fi- the emulation firmware of the Goldmaster 4140 v FTA (id 580).

Everything worked beautifully until yesterday when I tried to edit the TPS key in the code setting menu :

Whatever key I enter, the previous key (e6 7c ce e2 1d 25 e8 ff 31 88 ba 25 5b f0 07 ce) I loaded 2 months ago shows up....

I loaded the latest emu firmware GM-4150V_FTA (4/25/06) but get the same behavior.

I tried to rewind the firmware to a previous Topfield firmware without any success (getting an External Error...).

Any clue how to fix this problem will be welcome

Thank you
