Convert

The button “convert” isn’t active. What is the problem?

Well, with the over-abundance of information you’ve provided, it’s hard to say.

My 1st guess is that your player is not plugged into the computer. Or that is is not in MSC mode.

The player is connected but when I’ve selected a file to convert the right button  “start” doesn’t get active which means that I can’t convert the file.
