Raven Software's Wolfenstein has been patched to version 1.11, and you can download this from GP Downloads (44MB).

Changes include;

• Fixed issue resulting in user receiving gamex86.dll error
  
• Fixed issue that caused crashes when users broke numerous breakable objects during a Single Player Campaign
  
• Fixed issue that corrupted a save file after restarting a mission
  
• Updated the Wolf2.exe with a SecuROM fix that prevented users from launching the executable properly

Old save games will still work with the new patch, and you'll need to upgrade to version 1.1 before installing.
