I tried to start downloading songs and it came up with a licence agreement notice. I clicked always use the option but accidently clicked No to "Only download files with licences". Now i can't download anything. Is there anyway to change it back? I've tried un-installing and re-installing it. But it just keeps the same details. Sorry if this has been asked many times before.

See Revert Popups to Default but for mac, it's LW Preferences>View>Popups.
