Unable to enable CSSEdit "The plugin folder was not properly defined."

Vanilla 2.1
PHP 5.5
Scenario is as follows:
sudo wget https://github.com/bleistivt/CSSedit/archive/master.zip
sudo unzip master.zip
sudo mv CSSedit-master/ CSSedit/
Went to my dashboard>plugins and I see an unlabeled plugin at the top of my list. Mousing over the enable button I see that it is indeed CSSedit : http://69.173.125.39/vanilla/index.php?p=/settings/plugins/all/CSSedit/1BO4CODQ3UY8
When I click enable I get the following error:
"The plugin folder was not properly defined."
I tried following the previous advise from Bleistivt whereby line 3 of the class.x.x.php file has to have the name adjusted, but the name there (and through out that file) match.
Any help would be great!
