If I download Studio One 3 again from another PC and login to my account, will the songs/homepage appear as it was?

My system is down. All my files on my laptop had been deleted suddenly. I tried to download the whole programm again, which had worked successful. So I already logged in my account in but it is all deleted - the homepage in studio one 3 is completely empty.. is there any possibility that I can activate all my files again?

Please help me!
