Issue with Easy Contact Form log in

Can’t get into the plug in once logged into wordpress admin
I click on easy contact form and it says log in
I don’t know what that means. other than log in but I am logged in. This happened when we migrated the site over from another server the plug in has been strange ever since
I need to find where any logs would be stored from a customer trying to send me an email.

I read in another forum that you had to log in as the orginal admin when the plug in was installed but due to the security issues with wordpress we have changed the user names on a regular bases so I don’t have any idea what that log in is. It should except me as a administrator but it doesn’t want to.

It has a persons email contact information that I need to help them with some of our business products
Can anyone shed some light on this. I have tried to contact the plug in developer through their website and decided to post something here because I haven’t heard anything.

Is there someplace that this data could be other than inside the wordpress admin
Maybe on the server ftp or database?
I just need to see what email they wrote to us.
Hope someone can help
Thanks
