Hi Shane,

Thanks for getting in touch.

That's odd, that error always occurs when the zipped file uploaded is wrong and can be fixed by following the following steps.

Also check for server php errors using this guide: http://premium.wpmudev.org/blog/your-complete-guide-to-troubleshooting-wordpress/ . It would be best to contact the hosting provider and have them look into this as they are aware of the Server Configuration Details .

Hope this helps.
