I just purchased your template but I have problem installing your template.

I got the zip file (nzip_me_first_xxxxxxxxxxxxxxx_cosmo.zip), first I tried to upload and install this whole big zip file, it doesn't go thru. , then I unzipped this folder, then I got 3 zip files :


I tried to install the extension and quickstart zip file, but it still doesn't go thru., it says : "JInstaller: :Install: Cannot find XML setup file" and installation stopped.

Please advise what to do with the installation.
