unable to turn into a werewolf

[Steel Panther]

So I did the quests, was able to turn once, did not cure it, its been many days even got the uncursed ring if hircine, but I can't transform into a werewolf. I don't know whats going on with the game, also seem house carl from falkwreath has disappeared and having just done the quest to cure Klondike, Aela, Farkas and Viklas are no where to be found, so I have no clue whats going on with my game.

The very first time you transform, it's done for you. Every time after that, you have to manually select the Beast Form power and activate it (like you would a shout).

Once Kodlak has been cured, the Companions who accompanied you to Ysgramor's Tomb will take some time to travel back to Jorrvaskr in Whiterun.

If you really want to know where an NPC is hiding, you can use the console:

player.moveto <refID>

The refID for each character can be looked up through UESP[en.uesp.net]. It's recommended to save before attempting any console commands.

Yeah, I know how to do the werewolf change shape, it just won't do it. I fixed the problem with the Aela and the others with verifying the game files, I forgot about that and it seems a file got corrupted.

[Bomb Bloke]

Nah. Steam always redownloads at least one file when validating Skyrim, although it's not corrupt and it certainly has nothing to do with the Companions. Odds are you just ran out the timer on their return trip.

In regards to your transformations, you may need to provide your mod list. Also, have you attempted to disable any mods during this playthrough?

[Steel Panther]

I don't use mods. and most games I try to verify files generally don't download any. Not sure what you mean by ran out the timer, if you mean that I beat them there, I actually fast traveled to many places all across the map on that play after I did that quest. I ran the verifer again and it didn't download anything new but for some reason it's working right now so I don't know what was going on. Missed semi-colon in some line of code or something I soupose that reacted badly for a few plays maybe.
