Dungeon Siege: "Decoding Error - Compressed Data Is Corrupt or Unreadable" Error Message (321083)

RESOLUTION

Verify Files

To see whether the resource files are corrupted, run a cyclical redundancy check (CRC) on the files. To do this, follow these steps.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

1. Right-click the desktop, point to New, and then click Shortcut.
2. Click Browse, click DungeonSiege.exe, and then click Open. By default, the path is "C:\Program Files\Microsoft Games\Dungeon Siege\DungeonSiege.exe".
3. In the Command line box, to the right of the quotation marks ("), type a space, and then type verifydata=true.
4. Click Next, and then click Finish.
5. Double-click the new shortcut.
   
   The CRC takes several minutes to complete.

If any of the files do not pass the CRC test, the files are corrupted. To remove and reinstall the game, use one of the following methods:

   2. On the File menu, click Properties.
   3. On the Tools tab, click Check Now under Error-checking.
