You could look on the interactive brokers forum. Its problem that seems to comes up with new releases from time to time.
Hopefully you made a backup copy of your C:/jts folder so you can at least go back.
I had a problem not getting my hotkeys recognized. As a guess, I created a new page for ES with the same info as the old and I deleted the old page. Suddenly everything worked ok.
