Maybe it will be useful for somebody

I just wrote my id and it worked for me , maybe try that :)

try typing dizzee
not your steam name,but profile ID

It can not find your account by your nickname, but it can by:

• Your custom URL (for me it's Yusyuriv)
• Your Steam ID (for me it's 76561198062541451)
• Just your profile link (for me it's http://steamcommunity.com/profiles/76561198062541451/ or http://steamcommunity.com/id/Yusyuriv/)

Wow long before the service existed!

Same

Steam has no such data for some accounts. It shows "Unknown" now instead of 1/1/1970. Thanks for the bugreport!
