The last few weeks I'm having the issue that every time I start up iTunes on my windows pc, that I'm logged out of my account. Therefore iTunes match is also deactivated. So every time I start iTunes I have to relogin and reactivate iTunes Match. Anyone a solution? I don't have the issue on my mac. Also, my iTunes Match subscription is ending in december. I still have enough balance on my account for a renewal, but I assume I have to add a credit card to allow it to renew? But I hope it will take the amount from my iTunes balance?
