Statpress error

Having upgraded to 2.5 I’m getting the following error with the Statpress plugin:

Notice: Undefined index: REQUEST_URI in F:\Domains\mydomain.com\wwwroot\blog\wp-settings.php on line 81

I had to apply the following fix to the wp-settings page to remove “ERROR: Undefined index: PATH_INFO” errors on lines 74 and 77.

Just after the comment about IIS + PHP configuration (line 71) put this check:
if ( isset($_SERVER[‘PATH_INFO’]) ) {

and close the if statement, just above the comment “// Append the query string if it exists and isn’t null”

Any ideas how I could fix this? Thanks.
