Bassically I have had Steam for a couple/few years with nearly every Steam game on my account, last October it stopped working, it displayed the error:
So I went to the Steampowered.com forums and asked around and contacted the tech support, went through alot of things with them and they can't seem to assist me further, I also got help from a few forum members but they can't seem to assist me further either as they do not know what is wrong, and they stated its a generic error, meaning it could be anything, just to add tech support managed to log into my account on their computer so im really stuck, now for the things I have tried:
. Created a MSINFO32 report and sent to tech support, they say they find nothing wrong.
.Booted computer in safe mode
.Booted computer in safe mode + networking
.Checked router DMZ appears to be off
.Turned Windows Firewall off, both computer and connection
.Have a combo (firewall,AV,antispy etc PCGUARD) opened ports in the firewall, also turned it off and tried did not work.
.Tried Hijack this and other anti-spy and anti-virus programs such as house call.
.Tried a LSP fix
.Connection is fine works on other games online as well
.Checked ports on router, opened ones needed for Steam but it didn't make a difference open or not
Tried a few other things as well, but it made no difference no idea why it decided to stop working did not change anything on my computer, but just to add I did a scan with dslreports and it came up with certain things closed and UDP is used by Steam?
I just want this fixed its been long enough and I have got nowhere, im not the only one in the world with this problem, their are others but some just magically got it fixed others just gave up and unninstalled. If Valve would just research it that would be a big help, just to identify the source of the problem, but im left guessing and messing with things I don't want to mess with like the network as im not an expert on networking or routers.
So if anyone can help me thanks.
Also I have tried alot of things, so many things actually. Since Steam support is no use, im really at a loss on what to do.
