Uploading and installing problem

Hi there,

Just purchased Aqua and I’m having troubling installing it. If I upload the Aqua zip in theme uploads I get the error msg

The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

and if I log into FTP and transfer the unzip folder of Aqua into the wp/themes directory with the other theme’s it will come up in the theme list and I can activate it, but it gives Me the same layout as the default layout when you first sign up to wordpress. I’ve tried other theme’s and have had no problem but with this I’ve had no luck. I couldnt find another topic like this one, so some help would be appreciated. Thanks.
