ArmA Gold: bad serial number given

[LeeManatee 4]

I bought arma x on steam, everything works fine except arma: gold

yes, i run steam as administrator

yes, i tried to re-install it

when i check cache there is 1 file always failing to validate, says taht it will be reacquired, but it happens over and over.

i belive thats the problem.

The question is: how can i fix it?

Just go to search and put this line in the field:
