I get a big old question mark, as if the app is completely gone. I have re-installed 4.18 and I got it downloaded and installed but now it seems to have detected a non-existent firewall and won't let me get tunes. I'm pretty ready to give up. I am not as 'puter savvy as many here so I run out of options and ideas pretty quick.
Might ask if anyone here knows how to detect a firewall that isn't up.
