3.0.1 killed my site :(

The admin page told me to update to 3.0.1. Once I did, all pages (including the admin pages) now just say, “
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /home5/visualdr/public_html/wp/wp-content/plugins/wp-pagenavi/scb/load.php on line 12″

Help!
