OC expert needed to help me install export import plug in and theme

Hello, I need someone can help me to complete the installation of export import plug in and theme to my OC1.5.6 I am not sure why I couldnt manage, when I follow the steps of: 1. extracting zip 2. upload admin, system, vqmod from upload folder to oc directory via ftp 3. log in to dashboard of oc 4. system - users - users group, select top admin, edit and here I cant find the tool/export import in both access and modify dropdown list where I chould check the boxes.... with the template installation: I extract the zip, log in via ftp upload the catalog and images folders to oc, and when I would log in to the dashboard to go to system- setting and edit, go to store tab to choose the template I uploaded I cant even log in to the admin panel anymore.... to be honest the best would be if you could do it and tell me the way it was done. thank you.
