Logo stopped showing up

I have been using your WC Invoice for a while now and recently I noticed it stopped displaying the logo in upper left corner, I am using Template 1 for the base of my invoice and I tried making smaller resolution images and nothing, it was showing a X thru the image area, after I reduced the image size down to 150px it doesn’t show the X any longer but it shows nothing.
I also tried deleting the template and starting over, grab a fresh Template 1 and drop in a freshly uploaded 150px logo and it does not display there either.
Any help???
