Help Installing "Drift" Theme

Hi all, I put in a ticket with Audentio, but thought I would also ask here in case anyone has any experience with this theme...just because I'm kind of in a hurry.

I bought the Drift theme/style last night but there was no "read me" so I'm a bit lost. I'm using xampp, and decided to install the same way I did with Aurora- copy contents of "upload" directory, then install through admin cp. There were no xml files in the upload folder though, so I used the only xml files I found in the Drift zip file.

This worked to change the look of my forum somewhat, but there are a lot of big issues with it and this tells me I must not have installed correctly.

Can anyone help please? Thanks,
