You should try to connect yourself on Forkdelta instead of Etherdelta. On the other hand until and unless you remember the proper keys of your Ac you won't be able to access your account. If only one alpha or numeric key is shuffled you can not access your Ac.
When I made my EtherDelta account back in the days I instantly copied all the info to a notepad file on an USB
so I am just copying the exact private key from there and it's not working on Forkdelta and neither on myetherwallet
but I guess i should just forget about the few beers hehe
