I cant log in!!!

I deleted then redownloaded the app, and it tols be to log in... but it used my old @ (Erika___artist) and when I typed the CORRECT password it said it was incorrect so I said I forgot my password but entered my current @ (erikaneedsjesus) and I reset it and I went back to the app and Im still stuck!!! I use twitter 24/7 and Im VERY disappointed with this glitch!!!!
