Help, TwtDominator error.

I downloaded and upgraded TwtDominator. When I go to "Scrape Users" says "Please Upload Twitter Accounts to Start Scraping". But I do not understand because I already got my own and in "Account Actions" says: "Argentina654321 Exists".
Am I doing something wrong? Sry 4 my english.
Greetings
Edit: I tested with multiple accounts, and still giving error
