What filters are you using? We usually find more info about an error from the error screenshot in Summary tab. Hover over the word SCREENSHOT with your mouse, then it will show the error screenshot. It could be that the target account has 0 tweets or you have set the tool to like only tweets that are not older than 5 days for example, and the account hasn’t tweeted in a while
contact support with a screenshot of your favorite tool results and a screenshot of your settings.
What is the image of the error in Dashboard == Summary? When there are errors, you can hover over the word SCREENSHOT next to the error, and an image of the error will appear.
