I first got Crysis 2 about a month ago on my EAH5570 and it worked fine, after I reinstalled Windows 7 and used my EAH5670 I had a problem with crysis which was unplayable, I posted on this forum a few times but no one knew how to get rid of it, I sent the problem with a video to Crytek and they did not respond, then I thought maybe its my Disc, so I downloaded Crysis 2-FLT and used that installer, I installed the crack and logged on, it worked perfectly, so I removed the crack for the original and put in my serial and it worked like a charm, so I can now play crysis 2 online again (After I install all the updates)
