Single is down

Hello,


guys i´ll not lie so here it goes
i downloaded cod 4 :P (dont tell em to buy it cause i have no money)

i had a probs with multi , but now works fine, my prob now its with singleplyer
the rpoblem is quite simply though but its a bit ahrd to solve cause i tried to find everywere
when i put v.1.6 and v1.7 on multi it worked but on single dont , because it needs the dvd to works like a crack and i heard that theres a crack for v.1.7 and othr versions and you can get it just that i got to net and didnt found it , so can you guys find out another way to put single ok , or at least find me that crack for 1.7 version?

plz and thank you
