[Plugin: NextGEN Gallery] Fatal error in conjunction with Wassup plugin

I am getting the error, “Fatal error: Cannot use object of type stdClass as array in /home/content/c/r/a/(path)/html/wp-content/plugins/wassup/wassup.php on line 2421” underneath several NextGEN Gallery imagebrowsers. I have posted this error in the Wassup forums as well but I am not sure if it is their issue or a NextGEN issue. Any help would be much appreciated!
