Error code E10-0

hello im trying to download fortnite and it keeps giving me error code E10-0, product activation failed. ive tried deleting epic games and re downloading it and trying it again. I also tried restarting my laptop and my friend did it on his laptop and it worked for him but it just wont let me have it
