Did you uninstall and then delete the \wamp folder OR did you delete the folders and then uninstall?
You original problem woudl have been solved by editing the \wamp\alias\phpmyadmin.conf file and changing
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
To this
Order Deny,Allow
Deny from all
Allow from 127.0.0.1 localhost ::1
RULE 1. Ignore any tutorial/help that suggests changing anything to `Allow from all` unless you actually want to allow access from the whole internet, its lazy and normally point to someone who does not actually understand what they are doing,
As to your new problem, I would try Uninstalling again. Then delete the remaining \wamp folder and all subfolders.
Then reinstall. If the icon does not go green, post again and I will offer to TeamViewer into your system and help you solve the problem.
