What happen to XTRA - Multipurpose WordPress Theme?

XTRA - Multipurpose WordPress Theme + RTL

I bought this theme from Themeforest approx 5-6 months ago.
Today I attempted to login to download the latest version and Themeforest said this theme is gone?
What happen?

Is this theme got virus previously which led to being banned by Themeforest?
