Hi there,
It seems that when we tried to reinstall your EB, we hit this kind of error as shown
http://prntscr.com/c9o1ir. I have checked you folder permisson at [b]Backend>Systems>System Information>Folder Permission[ /b]. It seems that you set some of the status to unwritable. Can you contact your web hosting provider to set everything to "writable" except for "configuration.php". After all permissions is writable, try to reinstall it again. Please keep us updated if the issues still persist or not
