Install as per instructions and Network Activate (multi user, multi site).
In a regular blog I go through all the palava of creating ogg files from mp3 and completing the form. Click [Add] to add to playlist and :
Table 'testbp.wp_2_hmp_playlist' doesn't exist
Check with phpmyadmin and indeed it does not exist. Go back to Network Admin : Updates >> Update network figuring that that since the plugin is network activated that should force the creation of tables. But no.
