I purchased a game - Sid Meier's Civilization V from Best Buy. I installed it on my computer and it initally ran fine. I had a problem with my computer and Windows 7 crashed. I backed up my game on an external hard drive and also backed it up to Carbonite Online Backup. I tried to re-install the game and Steam sent me my Account name and I reset my password as I requested. Steam did not accept my account name, email address or my password not when I tried to input it. When I tried to contact support - I was again asked to provide my account name or e-mail address as well as my password. Same was not recognized by Steam. I have had to resort to installing Civilization IV but I am NOT satisfied as I want to play the latest version but cannot. Please register my complaint and help me.
