Hi. When try to manage !Joomlacomment and go : Components -> !Joomlacomment -> anything I've got error:

Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /users/marcingdula/www/http://spokogry.pl/administrator/components/com_comment/toolbar.comment.html.php on line 29

Before it works, but something went wrong. I tried uninstall, and install again, but it doesn't work. What should I do ?
