Also very late to the party, but I just encountered this issue on VS2015 Community after reinstalling Windows, and managed to fix it without upgrading IE. On the right of the window where it shows the trial status there's an option to 'Check for updated licences', clicking on this and entering login information worked where the regular sign in window failed.
