After WP4, I can't update the theme

Hi,
I’m trying to update the theme to 2.9.2, but I can’t:
· in automatic way: I have the message “No Updates available. You are running the latest version! (1.9)”
· in manual way: when I “Check Manually” it drives me for checking only the wordpress version, but nothing about the eunoia theme
What can I do?
Is it possible to get the these funcionalities (automatic & manual) again?
Thanks in advance.
Joan
