Error 400 - Bad request probably when library connects with microsoft api. #14

Hello, the library worked well but for some time, but like from a month ago some people receive error "Remote server returned error (400): Bad request" when using the lib.
This is the code on program entry point which returns error
try { LoginHandler lh = new LoginHandler(); this.session = lh.LoginFromCache(); } catch (Exception ex) { MessageBox.Show(ex.Message); }
maybe someone had simmilar issue or maybe fix is known by the library dev; I can specify more informations if needed
