Theme Check Errors

Hello there,

This theme has really served me well. It is compliant and built to stand the test of time. Recently there have been a few errors with themecheck and I was wondering if you might be able to address them.

REQUIRED: Text Domain: is missing from your style.css header.
Warning: More than one text-domain is being used in this theme. This means the theme will not be compatible with www.ads-software.com language packs.
