Oh DRM, how we love thee. Valve, the company responsible for the lifestyle game Modern Warfare 2, recently issued an apology to over 12,000 legitimate MW2 users who were accidentally banned from getting their first-person shooter on by the company’s DRM implementation. Valve’s president, Gabe Newell, wrote an email stating the the snafu occurred when an issue  with “a signature check between the disk version of a DLL and a latent memory version” occurred. We’re just going to go ahead and take Mr. Newell’s word for it. The email also promised affected users two copies of Left 4 Dead 2, one for them and one for a friend. Anyone out there get accidentally hammer banned by Valve over the last few weeks?
