Fatal error..

[busby]

I have installed XAMPP, and mostly it seems to be working fine..

However, MYSQL admin or Admin on the XAMPP contol panel won't connect and I get this error message:

Fatal error: require_once() [function.require]: Failed opening required './libraries/PMA.php' (include_path='.;C:\xampp\php\pear\') in C:\xampp\phpMyAdmin\libraries\common.inc.php on line 931

Also, MXSQL is running without a password, can someone tell me how to set one please or will that be in MySQL Admin when I get it to connect..

Many thanks in advance..
