Help restoring Drupal 7

I had a drupal 7 portal (made with a friend developer) 1 year ago. I wanted to move it from a share hosting server to a dedicated server. For that, I saved all the FTP-files and backuped the database (mysql) (with the module backup and migrate). On my dedicated server now I use PROXMOX to have virtual machines. I created a Turnkey virtual appliance for Drupal 7 in 5 min. Then I followed a step by step instruction to restore the database (phpMyAdmin) and I uploaded my ftp-files. My problem is that after that done, Drupal only displays the home page but all the other links/page doesn't respond or display white page. I need help to make it work. I think it is not big deal for a Drupal guru. If it is more easy I can recreate a new Turnkey virtual appliance with Drupal 7 and give you the db and ftp-files so that you can make the all process yourself.
