Double header after upgrade

I have just installed the latest version - now when I access arcade.php, I have a huge amount of visible code in the header.
No idea what the problem is (VB noob) so would appreciate some guidance.

This is what I see:

//------------------------------------------- // Creates a BOT session //------------------------------------------- function create_bot_session($bot) { global $DB, $INFO, $std, $ibforums; $db_str = $DB->compile_db_insert_string( array( 'id' => $bot.'_session', 'member_name' => $ibforums->vars['sp_'.$bot], 'member_id' => 0, 'member_group' => $ibforums->vars['spider_group'], 'in_forum' => intval($ibforums->input['f']), 'in_topic' => intval($ibforums->input['t']), 'login_type' => $ibforums->vars['spider_anon'], 'running_time' => $this->time_now, 'location' => $ibforums->input['act'].",".$ibforums->input['p'].",".$ibforums->input['CODE'], 'ip_address' => $this->ip_address, 'browser' => $this->user_agent, ) ); $DB->query("INSERT INTO ibf_sessions ({$db_str['FIELD_NAMES']}) VALUES({$db_str['FIELD_VALUES']})"); } //------------------------------------------- // Updates a BOT current session. //------------------------------------------- function update_bot_session($bot) { global $DB, $ibforums, $INFO; $db_str = $DB->compile_db_update_string( array( 'member_name' => $ibforums->vars['sp_'.$bot], 'member_id' => 0, 'member_group' => $ibforums->vars['spider_group'], 'in_forum' => intval($ibforums->input['f']), 'in_topic' => intval($ibforums->input['t']), 'login_type' => $ibforums->vars['spider_anon'], 'running_time' => $this->time_now, 'location' => $ibforums->input['act'].",".$ibforums->input['p'].",".$ibforums->input['CODE'] ) ); $DB->query("UPDATE ibf_sessions SET $db_str WHERE id='".$bot."_session'"); } } ?>='UserName' class='forminput' /> {$ibforums->lang['erl_enter_pass']}

ok - reuploaded files another 3 times and it seems fixed now - even though it was reading the correct new version, on of the files must have been corrupt.

All sorted now
