File Not Found, even though it exists!

Hi I'm making an MMORPG in DirectX7 (NOT DirectX9, simply because DirectX7 is easier). I have made a 261-frame rendered intro sequence, and I have placed all these images into a DLL, which works fine and has absolutely no problems whatsoever.

The problem is, when I extract the images to disk, then try and read them again in a surface loader, DirectDraw returns a File Not Found exception, even though the previous line of code tested the file's existence and found that it really did exist!

Here's the code:

Sub LoadIntro()

Dim k

Dim ddsdAs DDSURFACEDESC2

ddsd.lFlags = CONST_DDSURFACEDESCFLAGS.DDSD_CAPSOr CONST_DDSURFACEDESCFLAGS.DDSD_HEIGHTOr CONST_DDSURFACEDESCFLAGS.DDSD_WIDTH

ddsd.ddsCaps.lCaps = CONST_DDSURFACECAPSFLAGS.DDSCAPS_OFFSCREENPLAIN

ddsd.lHeight = 600

ddsd.lWidth = 800

For k = 1To LG_IG.Num_Frames

LG_IG.Image(k).Save(My.Computer.FileSystem.SpecialDirectories.AllUsersApplicationData +"\LegerDomain\intro_" & k.ToString &".bmp")

IfMy.Computer.FileSystem.FileExists(My.Computer.FileSystem.SpecialDirectories.AllUsersApplicationData +"\LegerDomain\intro_" & k.ToString &".bmp") =FalseThenEnd' The application NEVER exits at this point

IntroSurface(k) = DD.CreateSurfaceFromFile(My.Computer.FileSystem.SpecialDirectories.AllUsersApplicationData &"\LegerDomain\intro_" & k.ToString &".bmp", ddsd)' This line invokes a File not Found exception, although the file exists!

Next

EndSub

Any suggestions?
