i have an prob

...he has anything but Diablo, you are in essence right.

There are three "sets" of Gateways:

• Battle.Net Gateways - supports Diablo, Starcraft, Starcraft: Brood War, and Warcraft II: Battle.Net Edition
  Diablo II Battle.Net Gateways - supports Diablo II and Diablo II: Lord of Destruction
  Warcraft III Battle.Net Gateways - supports Wacraft III and, ultimately, Warcraft III: The Frozen Throne.<>
  [st]
  All Gateways for all Blizzard clients EXCEPT Wacraft III and Warcraft III: The Frozen Throne are found under

  HKEY_CURRENT_USER\Software\Battle.net\Configuration

  . Warcraft III and Warcraft III: The Frozen Throne Gateways are found under

  HKEY_CURRENT_USER\Software\Blizzard Entertainment\Warcraft III

  (presumably; for the time being, while beta testing, TFT has a seperate registry key under "Blizzard Entertainment", due to having seperate Gateways solely for the Beta). As such, deleting any of these would surely cripple his Battle.Net capabilities, for any game. ;)
  
  See my other posts for details on how to solve the issue. Barring that, I can create a registry file that he can import to very quickly and painlessly solve everything for him. :)
