Despartly seeking help…

I am having a problem that probably is easy to correct. I just need someone to tell me what to do because I am at loss on finding the solution.

Problem- At the top of my WP Plugin Pro there is a error message that reads the following:

Warning: Missing argument 2 for wp_plugin_update_row() in /home/charlesr/public_html/blog/wp-admin/includes/update.php on line 148

First I don’t know what a argument 2 is (unless its with my wife). I can locate the wp-admin/includes/update.php doc. But I am lost from there. I tried counting down to line 148 but not sure of what I’m looking for.

Any help would be sincerely appreciated.
