Need help fixing Instagram log in issue

When I try to log into Instagram from my phone or when i try to use FollowLiker, I keep getting this error issue: "The username you entered doesn't appear to belong to an account. Please check your username and try again."

Has this happened to anyone? If so, please help me to resolve it.

This all stemmed from when I was running followliker, I changed the password on my IG account (forgetting to stop followliker and update it).

Thanks!

I would contact IG now and hope for a speedy response.

they said there is an unknown ip address in tennessee that is accessing everything on my network. I'm trying to figure out if that is just FollowLiker.
