check yasr existence and get number/sum of votes

Hi,

Inside my single.php I used to use the method YasrDatabaseRatings::getVisitorVotes in order to:
1) Check if YASR is active
2) Get number and sum of votes

The code was something like:
if(class_exists(‘YasrDatabaseRatings’))
{
$votes = YasrDatabaseRatings::getVisitorVotes();
$number = $votes[‘number_of_votes’];
$sum = $votes[‘sum_votes’];
}

For some time now this code no longer works (the condition returns false).

Maybe the methods have changed?

How do I perform functions 1 and 2 above?
