Several days ago I bought a book from Google Play using the Android app on my phone. I then tried to sign in to the Play store on my Windows 10 PC so that I could download the book and transfer it to my ereaders. However, when I signed into Google and tried to access the Play store I got an error message.

I figured the Play website was just having a problem that day so I let it go for a few days and tried again today but I'm still having the same problem. I can access the store if i am NOT signed into my google account, but if I either
1) sign into Google and then try to access the store or
2) while not signed in, access the store (this does work) and then try to sign in I get the following error:

"500. That’s an error.
There was an error. Please try again later. That’s all we know."

I've tried both Chrome and Firefox. Also tried clearing history/cookies.
I'm not having any other problems with the PC.

Anyone else having this problem?
