Can I reset all settings?

Having a lot of issues and want to know if I can just refresh everything.

Issues:
* If I attach a featured image, then the post button doesn’t do anything
* The “add media” button does something that is beyond explaining here, suffice to say it’s not right
* The new posts show in the WP Admin, but not in the WPUF dashboard (have checked settings are for “Post”

Tried deleting plugin and reinstalling, but it seemed have remembered all previous settings.

If I can get this working I am keep to buy the premium version. If the premium version will override all the settings of the free version then I would be happy to just do that and give it a go.

Thanks!

Jamie
