Icomoon file won't load icons

Hi,

I followed your instructions on uploading the free icons via the Icomoon app. I select all icons and generate the file and download it to my computer. When I add the icons to BeTheme and select the .zip file, it gives me the following error:

This is not the Icomoon zip file. Please try again

It won't import any of the icons and tells me the icomoon.zip file is wrong?

Thanks,

Miguel
