Cant login to trello

[Greg Banach]

I have had troll for years.
I enter email and password.
Then Authentictor does not work. (I have two authenticator apps it does not say which one to use - I have tried both)
I try entering the 26 letter passkey. That does not work.
SMS does not work

I had to create a new account just to get access to this forum cos I cant log in and it seems impossible to get support from Trello.

1. How can I get my account up and running? Nothing is working.. 
2. How can I get help from Trello?

3. Which Authenticator should I use?
