ProPlayer will not activate

Hello,

I am unable to get the proPlayer plug in running (http://wordpress.org/extend/plugins/proplayer/).

I get this error code “Parse error: syntax error, unexpected ‘]’, expecting ‘(‘ in /nfs/c02/h08/mnt/25755/domains/estelavasco.com/html/blog/wp-content/plugins/proplayer/pro-player.php on line 65”

What’s that about? This is what is written on that line in the php file:

$id = $others[Constants::$ID_KEY].uniqid('pp-single-');

Help please. thank you!
