Everything looks good from here. I moved this thread to our technical forum. Please edit the first message to see a form where you can send us backend access info. We will help you to install the extension.
I confirmed the problem but I couldn't find a solution yet. Probably your server is blocking the access to our server. I'll need more time to investigate the issue. Please keep the access active and I'll back with an answer for you.
Thanks for your patience.
Best regards,
PS. if you need to update, do it manually as you do with any other regular J! extension.
I wanted to check what is wrong with installer but I saw that you didn't provided website FTP yet; can you please be kind to update this ticket and add website FTP? I installed an extlorer in admin but for some reason is not working so FTP is required for debug because this is not a common bug.
I installed a new iJoomla Installer version and now you can see the latest versions and license details. Please let me know if there still exist some issues.
