Steam problem

[zahnartz62]

ALL HAD BEEN WORKING WELL WITH COD UNTIL HARD DRIVE HAD TO be WIPED CLEAN AND DATA lost. I HAVE loaded COD via steam and it will not start. I uninstall reinstall waiting hours to be sure all DL by Steam. Will not start/ open. I get a brief flicker of a small steam winow does not last long enough to read.Submit prob to Steam, they say my email is invalid want new one I have only and desire only one..I am 76 and keep list of user/ pws by my PC. Has anyone a phone number? Must I use steam? I have the disk and had the Deastersoft loaded and ready now to install Team Fusion. Steam problem submission screen did not offer choice of subject to match my issue and refusing the email address I have used with them for some years seemed like a way to avoid helping someone. Please share you experience ...
