I am in the same boat. I am a A-10C Beta purchaser and should be able to get Nevada terrain. Installed the OpenAlpha, I activated the A-10C, then when I go to "Instant Action" to check out the new map, I get the "Nevada Activation" screen asking for activation code. I entered the A-10C activation code, but does not work. I also checked the DCS website under My Profile, where all my licenses are listed, but nothing there. What am I missing? Can't seem to find the answer in the forums, though there are tons of OpenAlpha questions....just have not found the answer to this one...expect I see the OP has same issue. Thanks.
