Evotec on "[Plugin: WordPress Download Manager] Bug - Mixed Content on SSL"

Hi,
on strict SSL Mode WPDM is trowing mixed content within:
?page=wpdm-welcome

To:
GET wpdm-extended-shortcode-200x200.png
wpdownloadmanager.com

GET wpdm-premium-package-200x200.png
wpdownloadmanager.com

GET tinymce-button-200x200.png
cdn.wpdownloadmanager.com

Sincerly Yours,

Deex

I see same problem. I've forced wordpress to SSL/HTTPS and right on Dashboard it shows mixed content problem pointing to http://cdn.wpdownloadmanager.com. Please release update with fix.
