my bad... its upgrade to 7.0.2
and yes, my AIP KEY is there along with SECRET and i set it to MASTER as well but still same thing...
it only happened with my old pairs... if i i start making new set of pairs from scratch, i can click to Exchanges bar and set it to my, which is Bittrex...
It must be some kind of bug... All changes i have to do manually in config file...
