ArcPAD 10 No datum transformation found from D_WGS_1984 to WGS_1984

Hey Folks,
i came accross a problem using ArcPAD 10 and Trimble GeoXH2008.
Whenever I add a MrSiD image (UTM projection) and try to activate the gps afterwards, i get the error message shown in the title. If I do it the other way round activate first and load image afterwards, it works, that just sucks if gps gets lost in the field, because you have to reopen your project and activate gps and switch image on again.
all transformation files should be installed and it still does not work,
maybe anyone stumbled across the same problem or could provide any advice?
Thanks,
Andy

A couple of ideas (these are comments, the suggestions haven't been tested):

1. Load the MrSID in ArcGIS and use a Define Projection tool and set the projection to ArcGIS's definition of WGS84,

-- OR --

2. In ArcPad use the Define Datum Transformation tool.
- Specify WGS_1984 and D_WGS_1984 as your Datum 1 and Datum 2 respectively
- Choose a transformation method, say, Geocentric_Translation
- Set all the parameters Dx, Dy, Dz, Rx, Ry, Rz, Xcr, Ycr and Zcr to 0
