Urgent, WP Smush Pro - images still not compressed....

Hi there

I bought the Pro version of WP Smush on the understanding that my images would be compressed much faster. It has been three days and the stats are saying that my image size has been reduced by 0.00 B( 0.00% ) and there has been no change over the last three days.

I urgently need to get the images compressed as I launch my new business site Friday and the site is incredibly slow currently

I would appreciate your help as a matter of urgency
Thanks
Ruth
