Then you should also try:
Operating System
-Upgrade it! Get the latest service pack blah blah etc
DirectX (Non-XP only)
-Uninstall it, and re-install the version on the disc! For details on how to uninstall it, see here (

CPU
-If it's over 1ghz, then this problem may derive from Grim despising your ultra-fast processor. Get CPU Killer (

CD-related problem?
-Copy all the files on your CD to your hard drive.**
-Now click "Start -> Run", type "regedit" and hit Enter.
-Browse to:
HKEY_LOCAL_MACHINE\SOFTWARE\LucasArts Entertainment Company LLC\Grim Fandango\v1.0\
-Right click and select "New String Value". Name it "good_times". Now double click it and type "TRUE" in the Value field. The game will now run from your Hard-drive, and this could potentially solve your problems.
*There is an unproven theory that DirectX 8.1 is the cause of Grims troubles, and also some talk as to whether it may be an incompatibility with nVidias graphic cards. If you have XP, you can't downgrade from DirectX 8.1, as that's standard. Also, if you can't run Grim Fandango from the pop-up splash screen, try running it by double-clicking "GrimFandango.exe" in the default Grim directory.
**If you can't do it in explorer, try using Isobuster (
