Hello again Nila,
I can see now that you do not have a cloud node installed which is the reason why you cannot see your company on My Standard. In this case I recommend that you export a new database text backup from your old computer and reinstall Standard ERP on the new one and then try to import the backup again. It is possible that some error occurred while you tried to export or import the backup. I also recommend that you download the absolute newest version of 8.3 from 2017-01-25 while you are at it which contains a few fixes that aren't available on the version from 2017-01-08. You can find it at www.standardinstall.com
Kind regards,
Edwin
