Apple Music on PC isn't detecting my subscription.

Hey guys, what's up? So, I have a family subscription on Apple Music, but today (05/10) I tried to use the service on my Windows 10 laptop and it didn't work. Idk if it has something to do with it, but 2 weeks ago I lost my iPhone 5s in a music festival and hadn't been able to recover it, so I'm using my old iPhone 4 (which don't supports Apple Music). All my family members are having no trouble using the service on their cellphones, but they haven't tried it on the PC.

PS: my iTunes PC app is updated to the latest version.
