Created Unassigned: Validation fails - Credentials Invalid [20494]

Hello -
I am using the AutoSPInstallerGUI to generate my "AutoSPInstallerInput.xml" file. I have went through the instructions thoroughly and searched the support board here, but I cannot seem to find what is causing my issue. I run the bat file to kick off the install and when I do it never makes it past the Account Validation portion. It keeps failing with the error;
- Account ""...Invalid!

It does not reference which account and it clears through and verifies my farm account, my managed accounts, my search service account, my excel services account and my PerformancePoint Service account.

I have no accounts in there that are blanked account that are configured to be used, and I am attempting to use this to install SharePoint 2010. Below is an actual copy and paste of the error output....
