I am getting an "Error: HTTP call failed: LOGIN" message using TD Ameritrade since upgrading to the lastest Version of NinjaTrader.
I did install the latest version since the advisories last week and for trial I re-named the config.xml to let NinjaTrader create the file again. Login worked once and then failed again (I have tried for several days).
Should I / Can I go back to a version prior to 14 ? Any help would be appreciated.
