The updated ZIP file should have been mailed to you, which contains the new icons and so forth that were missing in the last zipped file

. If you did not receive it, shoot me an e-mail (saintdog[at]vbtdesign.com) with your PayPal Purchase ID and I will get it mailed to you.
As for redoing the style, as long as you are using the style as a base or the graphics from the style, the copyright and so forth is still required as per the license agreement from vBTDesign. If you purchased the copyright removal, then you are free to remove such instances, though if you did not, then it should remain in tact.
While you did "redo" the graphics, the graphics that have been redone are replicas of what was included with the styles (though with different colors), originally made for the skin.
Not trying to be rude, just have to set the rules even for everyone. I had another customer do the same thing, of which did not purchase CP removal, and he was required to do the same thing.
