So I'm trying to buy Tori Prime and VIP through the shop with Steam, and I keep running into this issue. When I switch to the steam payment option and I get the pop-up telling me to sign in through steam and I click it. I put in my username and pass, click sign in, but I get an Error message every time.

I'm using the right log in information, I've tried clearing my browser's cookies, but its still not working. I've made a purchase from the shop before using steam a long time ago, but its not working for me now for some reason. Also the browser I'm using is Google Chrome. Any idea how to fix this so I can make my purchase?

Which item are you trying to buy?

I said it above, ToriPrime and VIP.

I tried clicking on something else as well, some blood, but ran into the same issue.

Try buying any item from the ingame store, you don't need to confirm the payment just check if the steam popup shows up correctly
