I have played about 48 hours into Skyrim and while I have noticed some small bugs, there is one that is driving me mad as it is totally breaking the main quest line. When I try to complete "The Horn of Jurgen Windcaller" I cannot receive the greeting from the Greybeards. I discovered, after watching a YouTube video of that event that there are supposed to be 4 Greybeards and low and behold my game only has 3. I have looked everywhere for said 4th Greybeard but he is simply not there. I went ahead and completed the next quest of Alduin's Wall and when I am sent to speak with Arngeir about the dragons I am still stuck at the damn greeting phase of the first part of the main quest line and still have a missing Greybeard. Tech support asked me to verify the integrity of my game cache on Steam and lo and behold "1 file could not validate and will be reacquired" is the result. Now I have done everything I can think of to get Steam to "reacquire" the file but it simply will not do it. Anyone know what to do next?

PS - the missing Greybeard is Borri. Wulfgar, Einarth and Arngeir are there.

Welcome to the forums

The missing file is related to Steam, not Skyrim.

Would be a good idea if you could first determine which Greybeard is missing - Arngeir, Borri, Einarth or Wulfgar ?

P.S. OK - while inside High Hrothgar open http://www.uesp.net/wiki/Skyrim:Console and enter the two commands
