Well I have never run into that before. I would suggest just uploading uploading the br5/5.5/6/6.1   .....which ever flavour you use to that slot and if it's over th 10M limit zip or rar it up...I never really noticed that box when building the contest and am certain I didn't select it as it says nowt in the rules 'bout it so am assuming it's there by default. Let's humour the machine and try my suggestion...LOL.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
