Ultimate Branding - Admin Login Logo (310x70) Not Showing Up

Morning!

I downloaded and integrated the Ultimate Branding plugin a while back. Everything has worked just fine and dandy except for the admin logo/image upload option.

I have double checked that my admin logo dimensions are within the parameters needed to be able to display the image. Yes.

I tried using the other custom admin logo admin plugin listed as plugins on WPMU Dev and it didn't work either. Although it is saying (for both plugins) that the chosen image has been selected and loaded. And I have visual confirmation that it has been selected and loaded on the admin back-end.

Will you please advise?

Thank you.
