I'm trying to import a shapefile into a PostGIS database using the graphical importer. I just installed POSTGRESQL, and PostGIS. The GUI looks like this:

After testing that my database worked, I chose the shapefile that I wanted to upload, and then received a message that it had failed to import. I tried tweaking a few paramaters, but I'm not sure what I'm doing.
Are there any good tutorials or instructions about how to do this? I'm using Windows 7 64 bit.
Just adding a little more of my error message.
