I bought Borderlands 2 from steam and was able to set it up successfully on my system. However, the monitor later went blank and when it returned it came with the steam_api.dll is missing error message requesting that I fix the issue. It also instructed me to have the game reinstalled. I found this highly unusual considering the fact that there was no sign of this problem when I first installed the game. I decided to verify the game’s cache. In addition to being a lengthy procedure, it also ended it futility. As soon as I completed the verification, I had the game reinstalled but nothing changed. I decided to check out different online tutorials and came across the authorised Borderlands 2 forum on steam. I discovered that a lot of people faced the same issue. The good news is that most people were able to fix the issue with the solution described below.
