Advanced Access Manager – Broke Admin Dashboard

I allowed an update to Advanced Access Manager and it completely broke the admin dashboard. I was getting 404 errors on any of the admin pages, Users, Profiles, etc. Plugins completely disappeared from the menu and I received an access denial when I tried to access the page directly.

I do not recall which version but it was an Alpha release. I tried every setting combination and still could not get them to work.

I manually removed the plugin and directory which as expected removed all access to admin widgets.

I manually uploaded Advanced Access Manager v3.0 Beta into the plugins menu and it started throwing parsing errors when I tried to start any of the other menu items. I renamed the directory and now I can use the items still showing on the admin menu.

Direct URL access to the plugins page returns an empty page.

I need two things:
1) Instructions to manually install a STABLE version of AAM or effect a refund and help eliminating all changes made by AAM.
2) Instructions to gain access to my plugins if # 1 fails.

I am the owner of the site and it is privately hosted. I have direct and FTP access to all files.
