to trouble shoot an error message, i'm trying to upload the stats file to alp. But three tries with two separate fat 32 thumb drives failed.

I tried to follow the directions from website.
Maybe I didn't do it correctly

please clarify between "next" button, "enter" button and "menu" button

My control panel has only two buttons:
left button has an on-off symbol
right button labeled menu

which is "next"
and which is "enter" ?

thank you for help
