TF31002: Unable to connect to VisualStudio Online with VS 2013

but I can using web access - Windows 8.1.

 FIX:

1. Close all instances of Visual Studio 2013 2. Delete this folder in the registry (just “TokenStorage” – nothing else):

HKEY_CURRENT_USER\Software\Microsoft\VSCommon\12.0\ClientServices\TokenStorage

regedit-到注册表管理

VS2013无法链接到TFS(Visual studio online),错误TF31001,TF31002
