I just bought Arma II Combined Operations from Best Buy yesterday. I put it in today to install and play it. The enter cd key box popped up and told me where to find the key on the last page of the manual. I found it and started entering it when I noticed that after the first 3 strings of letters and numbers there was no dash leading to the 4th string of letters and numbers. All there was was a space like 3 or 4 spaces and the the letter N with a dash after that and then the last string. I tried every combination including putting the spaces in, no spaces, caps, no caps, etc. Nothing works so I cannot install the game. :mad: I called Best Buy and they stated that they would not take the game back as it has been opened. I decided to try the Arma II OA disk and that installed with no problems at all. What do I have to do to get a working key? I have already e-mailed tech support for the game and haven't gotten a response. Any ideas?
