I had to but a new laptop, my old one crashed. But now i can not remember how to download my package...
You can install Logos 4 from here: http://downloads.logos.com/LBS4/Installer/Logos4Setup.exe If you still have the old backup you might want to check out this article to save some downloading http://wiki.logos.com/Quick_Installation_onto_multiple_computers. If you have upgraded to Logos 5 you should be able to see that download link in your order history.
Welcome to the forums Diana. If the laptop has Windows Vista, Windows7 or Windows8, it is highly recommended that you install Logos 5. It is a faster platform. http://www.logos.com/support/logos5/windows/install You will have access to all of your resources, and there are training videos to explain it.
Furthermore, sign in with the email address that you used in Logos 4.
Happy downloading.
