[mapguide-users] Raster (SID / TIF ) Images not working !

Hello, I am fairly new to MGOS, and I am having problems getting raster
images to work.  I am using version 1.1. I installed all the dlls from
http://trac.osgeo.org/fdo/wiki/FdoGdalNotes

Note that in my development environment we have MG Enterprise setup and the
rasters worked fine. 

I have both sid and tif versions of the raster images I want to use, I have
tried both with the same result. They just do not display. Everything else
works. I have 2 raster layers setup, with differing quality images, I have
set them up so one uses SID,and one references the actual tif files. Below
is a excerpt of the debugging. A few errors in there. I know there was a
previous post referencing the Can't find RasterDMS field / IReadBlock failed
error, but the solution in this previous post was to change the GDAL13.DLL.
This should be changed in my setup (version is dated Jan 28, 2007). 

Any Ideas ??
