I purchased Arrowhead DLC from Gamestop and have had a very bad experience with their poor customer support in providing the serial number/cd key. Also I have spent all day trying to patch up all the way from 1.50 and still I need to uninstall and start over. Anyway,water under the bridge, I'm done with their version. I am willing to sacrifice the 20 dollars I paid to Gamestop and start fresh from a different 'portal?'. Do I want to purchase a boxed CD or is DLC fine and least problematic as long as I pay/download via Bohemia? How current could I expect the updating within the initial installment as I want to navigate the least amount of patches possible? Basically I need someone to take me by my wet ears and guide me. And the magic word is PLEASE.
