Cannot log in to MQL5 from inside terminal

Using the same credentials as web platform, I continue to get the message incorrect username/ password

I have reset the password, and still to log into MQL5 from inside the terminal isn;t working... I use the same for MT4 and am logged in without problem?

Do I need a different USername for MT5? I'm not usually a dummie when it come to tech, but I'm stuck here?
