How to manually uninstall Advagg?

I’ve been searching all over the internet trying to solve this with no luck.

I was tweaking Advagg 8.x-2.0 settings, and I remember clicking an option that said “use in the admin toolbar” or something like that. After applying, when I’m logged in, I can’t see any styling. Only a long white portion of the page, and, at the bottom the text without css.

I use XAMPP, and don’t know how to install/use Drush, yet.

1- If I try to uninstall the module clicking on the unstyled text it says: The form has become outdated.

2- If I try to flush all caches, it says: Access Denied.

3- Is there an alternative way to uninstall the module manually without Drush? I’m using windows 8 and XAMPP.

4- If I log out, everything shows ok.

5- I remember having Ajax enabled in some views, including the landing page.

Chrome Dev Tools shows the next errors:
