Sharing is helping.

We offer you this space to share your knowledge about Magento and learn from our experienced customers.

    We already uploaded the new files, but if you want to avoid downloading the files again you should
    try extracting the .zip file of the theme, then change the name of the extracted folder to the same one it had but without the capital letters (ie: HelloUno to hellouno), then zip the folder again and try with that new one in the hello upload.
    Remember to change de permissions of the magento app/ folder to 777 (read, write and execute).
