enewsletter deactivating my site theme

E-newsletter *was* working.

this morning I duplicated a custom theme & changed the directory name and the theme name in the style.css

(stored in uploads/enewsletter-custom-themes -- running from site1 on a multisite)

Suddenly, the plugin crashed and deactivated my site theme.

I had already saved and tested one of the emails. Odd that it reverted to the cloned name after the crash.

Site theme is genesis with a child theme

I've tried removing my custom themes and creating a new newsletter (instead of cloning).
