As the title says for the past few weeks (maybe longer) every couple days Spotify informs me that my local access for my computer has been withdrawn. Then I look in my settings and I notice my cache folder location has returned to default. Once I change it back I can start redownloading my songs to local, although they always get stuck at some point (with a few hundred left to download). I only use Spotify on my own computer and a tablet (occasionally I use the web player elsewhere).
I have Spotify premium and use Windows 8.
I've cancelled my premium subscribtion for now, I'll restart it if this problem is ever fixed.
