Doom 3 will not start, wants product key

[stern-69]

I purchased, downloaded, and played it yesterday with no issues. When I try to run it today it pops up a screen asking for a product ID code on the jewel case. That isn't going to happen as it was an online steam purchase.
Any help would be appreciated

Doomkey and ROEkey files:

If you use the RMB in your Steam Bibliothek at "DOOM 3" left side or LMB under "LINKS" right side, you finde something like "show productkey" or "productkey"!
This key must be in "doomkey" file.
Normaly it should be there after installation, done by steam.
If it is not, make it !!
Maybe deinstall and new installation may help!!

• Only for not starting DOOM 3:
  look for textfile "doomkey" without extension in
  .......STEAM\SteamApps\common\Doom 3\base\doomkey
  Your key must be in doomkey!! - if not copie your key into doomkey!!

• Only for not starting DOOM 3 Extension ROE:
  look for textfile "xpkey" without extension in
  .......STEAM\SteamApps\common\Doom 3\base\xpkey
  Your key must be in xpkey!! - if not copie your key into xpkey!!

Content of "doomkey" or "xpkey" :
