I've had steam installed for a year now and well the damn thing stopped working tried a reinstall that did not work, put it on my lap top its working fine, tried plugging in the PC directly to the NIC cable and that did not work tried using wireless that did not work. Also got a data corruption issue when I try and install it now...and yes I tried a recovery point..... 0-o And yes its cleared in Comodo firewall. I am at a loss to whats blocking it MSE is not installed and or off.
