would this happen to be this chappy here o.O
an interesting note is that i recieved this:
a few days ago,, shortly after I started getting the mss32.dll error,,,
also I know this is not related to trials but since then I`m now unable to play halflife 2 (steam again) in 64-bit extended mode as the games npc ai is disabled...
just adding my 2 cents..
I have also sent a support ticket to valve escalating the problem it reads
"Hey guys,, a few days ago I received an error when attempting to start game "trials 2:second edition" that there was a steam error and it was "unable to contact key server".. a restart of steam fixed this problem and I was able to start trials,, now on starting trials I get a popup windows error box that a dll file mss32_s.dll is missing,, the game still starts if you press ok but obviously somthing is not right there,, further to this since this error occured the 64-bit extended edition of halflife 2 which I have been playing for ages now refuses to work as you get the error "ai is disabled" ,,, i have to run hl2 in 32-bit mode obviously to play the game correctly.... I know that redlynx have/or are contacting you regarding this matter but I`m just relaying what information I have noticed in the process of this problem also... I would be greatful if you could contact me back on this matter for a fix/solution, or any other helpful information, I would also happily try suggestions to see if they work. Thanks, Douglas Mcarthur"
I have also enclosed the 2 pictures above to let them see the errors,, hopefully they`ll get back to me and I`ll post here what they come up with
