I've re-uploaded the latest Cosmo 3 setup with the fixed templates. And you can also grab the templates attached here, simply save them over the existing ones in C:\ProgramData\Profantasy\CC3Plus\Templates\Cosmographer\Wizard\

Please don't advertise your products on our forum. If you want to discuss use of CC3+ and its add-ons for use in virtual tabletops that is fine, including showing some screenshots how CC3+ maps works in your map. You can even link to your site, but the discussion has to be mapping related.

The button is there because some people want to clean up their registration lists - removing old products that are not required anymore.

It only deletes the product from the visual list. It remains registered to your email and if you want to transfer it someone else (which you can), you need t notify us, so we can properly move it to their registration.

You can always re-add a product to the list by taking the serial number from the Orders tab and pasting it on the Downloads tab.

If you extract these symfill files in your /System/Fillers/ folder overwriting the existing ones, does that solve the issue?

The corrected setup is uploading and here are the two corrected templates.
