Contrast isn't good, you need to brighten up the gold. Also, replace comma with ampersand--if the font you're using doesn't have a nice looking ampersand, try different fonts just for the ampersand.
When you've got everything looking good, adjust the font size of "The Gold Standard..." line of text so it is exactly as wide as JW Digital Archiving. Looks neater that way.
Finally, ditch the image. It's too small and awkward. Old rule when designing a logo is to design it for a business card first. If you'd done that, you'd have realized that the image would have been illegible and dropped it anyway.
As a more casual and modern look, don't capitalize all the words in the slogan.
Edit: Here are examples of what I mean:

Can't ever read the black-on-gold version in large print, it would be nearly invisible on a biz card.
The gold-on-white is an improvement, but the sans-serif font your using is too heavy. Try Helvetica Neue, it has a lot more weights.
And why'd you pick the art deco looking font? Thought you were trying to express how modern your company is.

I don't think the original gold-on-black was that bad it just need some tweaking.
