I am trying to update Hijack with jEmplode and am getting the following error:

You must have Hijack version 242 or higher, be connecting with jEmplode over Ethernet, and 'Use Hijack when Possible' enabled under Tools=>Options...to upgrade Hijack.

I have Hijack v838 installed on it right now, I am connected to it over ethernet: can telnet in, view web interface and sync with jemplode everything. Under tools and options I have that box checked. Its worked before at home but not at work. anyone have any ideas? Thanks
