We cannot offer support for the Pluginlabs CSS Menu extension. here.
Did a bit more looking - originally I was thinking is was part of a webassist extension but I was wrong - my bad. This was purchased from Plugininlabs ($200) and the company is virtually dead now so online activations are impossible after the fact. Lesson learned here was do not make purchases from companies that require online activation without system in place to allow users option for manually registering.
thanks for the reply.
