Even with an updated key, you may face issues. Here is the troubleshooting guide.
Lost your original key – If you have an old DVD copy and lost the key, you cannot get a new one officially. Support will not issue replacement keys for such old titles.
Looking for cracked / offline play – That’s outside ethical/legal discussion here, but even then, “updated” makes no sense — CD keys don’t get “updates”; game patches are separate.
Before diving into keys, let’s clarify the product. Arma 2: Reinforcements is not a standalone game in the traditional sense. It is a combined DLC and standalone pack released by Bohemia Interactive in 2011. It contains two major expansions: Lost your original key – If you have
