So I have the game installed at home, I work in a campus computer lab and would love to be paid to play demigod all summer...

I can drag my demigod folder onto my flash drive (8gb), and i can run the game from there just fine, however when i go to play online it says "you need an update" but the game itselft shows version 1.20.xxx (the current one as i play online at home). 

Is there a registry key i can add? or what am i missing to allow demigod to see itself as up to date so i can play online.

Alternatively any suggestions on playing on a computer I do not wish to install programs on? (such as install to an external from the current (work) machine so the registry keys are created).

Thanks much for the advice!
