Hey, @zachbtemp, @LetterT please open the admin/meta-box-class/js/meta-box.js and find line 358:
line: 358 tb_show('', 'media-upload.php?post_id='+ jQuery('#post_id').val() + '&type=image&TB_iframe=true');
change by:
line 358: tb_show('', 'media-upload.php?post_ID='+ jQuery('#post_id').val() + '&type=image&TB_iframe=true');
we will fix that issue next update.
