Hello,
I just registered and I am attempting to import my steam library.

I copied my steam profile address into the steam section under settings.
But when I test the link, it cannot find the profile.
I receive the same report when I try to import.
The exact same address works just fine when I paste it into my browser.

I am hoping there is something obvious that I am missing.

Thank you, in advance, for your assistance.

On the Account Settings page, you just need to enter your profile name, not the entire URL. So in your case, you should just need to type in this: 76561197998526017
