The first thing that comes to mind is that the package is somewhat big and 1&1 is a slow host, which means that the installation will take very long. Add Joomla!'s FP layer to the mix for extra long installation times. And PHP 5.2 is 7x slower than 5.4, which means even longer times to install the component. Combined with a low maximum execution time limit it most definitely leads to a timeout error which causes the infinite spinning. You get the picture.
Your best bet to get it installed is the manual installation described here: https://www.akeebabackup.com/documentation/troubleshooter/abinstallation.html (towards the end of the page, under "Manual installation").
