Apple Music Won't Work on PC

Up until recently, Apple Music had been working fine on my PC (it runs Windows 10), until two problems arose. The first problem was that none of my music would play. Instead of the songs playing, the bar where it shows how long the song is is in blue instead of allowing me to skip around to any part of the song. This was never fixed, but the problem I'm facing now is that I can't access my music at all! It's constantly says "Accessing iCloud library," but it's been forever and it still hasn't loaded my playlist. Apple Music works just fine on my iPhone and Macbook so I'm no sure why this is happening. What should I do?
