The fact that $E_6(e^{\frac{2\pi i}{3}})\ne 0$ is considered to be obvious in some proofs of the facts about the Eisenstein series that I read, but I can't see it myself.
Please, help me to make it clear.

How to prove that $E_6(e^{\frac{2\pi i}{3}})\ne 0$ where $E_6$ is the Eisenstein series of weight 6?
