Guys, I got mine fixed. what i did was that i copies all files in junkies folder/steamapps/common into steam's folder i had installed into Steam/steamapps/common. Then i took my friend's ID who had bought this game through steam and downloaded and updated it. Then i again copies to junkies folder at initial location and ran junkies client and just updated it. And tada it worked again. So basically i just updated it to latest steam version through steam and then patched it again.
