Not being able to login, as your initial post claimed, is very much a different problem then not being able to access the login page, as later posts seem to indicate.
I don't know where you uploaded your wordpress files, but you did most definitely not put them in /domains/DOMAINNAME/public_html as in that folder I can only see the default files that was created with the domain. In fact, it would appear you never did upload the files onto x10hosting, I don't see them anywhere in your account.
The database is only one part of what makes up your WordPress install, there's a lot of files/folder (including all images and other media you put up in your blog articles) as well that you need to backup at the old host (download as compressed file) and then restore in the above mentioned file path. Without the files nothing will work.
This is likely going to be a larger file, especially if you have many images, so uploading by FTP may be your best bet. You can afterwards use the file manager to extract the files from the archive. Make sure that the files are extracted to the root of the above mentioned file path "/domains/DOMAINNAME/public_html" (if they end up in "/domains/DOMAINNAME/public_html/backup" where "backup" would represent the name of the archive in most cases, you would need to move them into the proper place
You will also need to edit the file called wp_config.php to reflect the new database name and the database user and pass you set up here on x10 hosting. This file should be in the /domains/DOMAINNAME/public_html folder if you correctly restored the files from your old host.
