I cannot seem to get bittrex to work. I generated my API keys, go back into the CAT and every time I attempt to login I get a User Not Found message... anyone else having this issue with Bittrex?
Trex is working fine for me - did you enable trading on the API key and follow 2FA/verification procedures whilst setting it up?
Yes, I've used it in the past. I even generated my keys again just to be sure...
that's the problem, you must not change your API key. CAT works only with the API you activated in the past.
It's clearly written in the Term Of Service "Do not change your APi key"

Can i resend my new key? I apologize for my stupid mistake... ;-(
