Re: We don't recognize the computer you're using

This Sounds like a troublesome problem. Try adding the points directly from your console.

Hey! VTanimefan let us know if you do still have trouble adding those points on the console!

The Redeem Code in the XBox Live menu on Xbox.com works so I am able Redeem prepaid codes however you can not purchase through that link which is what I would like to do.  I will try purchasing through my console but would really like to be able to purchase points through the computer.

Already done that with no luck.  It is something with the Xbox website that they are working on.

Guys, I'm having the same issue, how can I fix it?

I'm getting the same error with every purchase since I started using the Windows 8 preview. Build 8400. I'm tired of entering the codes sent to my phone.

i had same issue, i think xbox live just wont let you put microsoft points on your xbox account from a pc or laptop.

I've purchased points many times before on my PC. My problems only started recently. Browser? I'm using Waterfox (64 bit Firefox) and have used it before to get points. I normally used the Zune software to get points. I have used the browser a few times. Using Windows 8 preview is the only big change on my PC, and I did import my settings during install. This could be a Win8 problem for me.

I get the message by simply selecting the option to buy more points. I get a code on my phone to enter and then I can continue, but it's every time I want to buy points since installing Windows 8 Release Preview. It's before I even start the process of purchasing anything.

Where do I reset the security options? I followed your link, but nothing looked obvious to me.

Thank you.

Mine is finally working after waiting 30 days for my security information to be cleared.  This seems to be the only way to fix it.
