Welcome to WebmasterWorld 2kegx!
Try adding two separate sitemap files in Google Webmaster Tools. Google does give a bit more error feedback there in my experience. There are a number of online tools to generate them.
The most common usage of multiple file reported here is on huge sites that exceed the 50,000 entries per file limitation. Others have used them in hopes of enhancing deep page indexation. Some have used them to resubmit pages recently moved.
