CMS Made Simple - Exported from SitesnStores(Plesk), Need to install and Import to CPanel

BID ONLY IF YOU HAVE EXPERIENCE WITH CMSMS (CMS Made Simple). I have a customer who is hosting with sitesnstores, where they use CMS MadeSimple, They are moving across to us as a web hosting provider, and issues importing the database and files to cpanel, We have a backup of the SQL dump, and the httpdocs from SitesnStores(they used Plesk previously) We need to install the CMS Made Simple, Import the database, and put the files in for it to be transfered, there are a few errors that are coming up when importing data and browsing to the site, For example error message here: [login to view URL] For someone who knows their way with CMS Made Simple and what they are doing this should be fairly simple,
