Only old tweets not refreshing

Hi,

Nice plugin, Im using it in the footer of my site here
snackboxfilms.ie, and it was showing the latest tweet when
i started using the plugin, but has never showed a newer one.
So it’s not refreshing. Everything seems configured and correct
in the settings section.

Any advice?
thanks in advance
