Why it destroys the layout of WP gallery?

Bought and installed your plugin.
All WP galleries became distorted, no gridview, no thumbnails, all my website basically destroyed, images are all over the posts, by one or two o simply separated by enormous gaps…

Deactivated the plugin and all WP galleries in posts cameback to normal view.
Please explain why it is so and if this cannot be resolved I want a refund.
Please dont tell to contact mike, have read your forums, he simply never knows the answer.
Thanks
