I am having trouble loading a raster (.asc) file to PostGIS 2.0.1 using the plugin Database - PostGIS Raster - Load raster to postgis in QGIS 1.8.0 on Win Vista 64 bit. I get the following error message:

QGIS opens the file just fine.

Any suggestions on what to do?

I have two hypothesis: 1) It seems that there is a problem with your PYTHON_PATH environmental variable. The variable used to tell Python where the installed modules and libraries are. I think you have to define an environmental variable pointing to that path. 2) It could be also that you have not installed the GDAL wrapper. Try to import it in a standard python console (using: import osgeo.gdal) if some error happens it means that you need to install gdal python wrappers.
