```

Any suggestions? (I tried re-installing but the same issue shows)

Answer: 
Update to to IE 11 and everything will work fine.
Update of IE is not an option for me. I need it for testing on this machine. In my case following helped me:

I opened developer tools of IE8 (press F12). It was in 'IE8 Compat View' mode. I switched to 'IE8' mode and specified Document mode to 'IE8 Standards'.

Then I were able to sign in to TFS through IE8. Once I signed in using browser I restarted Visual Studio and everything worked correctly.
