[Plugin: Countdown Timer] CSS – Class or ID for each time increment.. not counting

Hi to everybody,
first of all thank you for the plugin.

I followed this topic to change Class for each time increment
http://wordpress.org/support/topic/plugin-countdown-timer-css-class-or-id-for-each-time-increment

but i had to switch off JavaScript countdown, so now i got almost what i wanted, but countdown it’s not moving when I’m on the page.

Here is the testing page:

I didn’t find any answer on the forum

Tnx in advance
