Check the app's permissions in Settings/Apps. If there's a wakelock permission, enable it. Otherwise, I'd say it was a poorly written app - at least the message should be worded a little more clearly. (And it's way below my pay grade, but I'd still report the app as "I won't be using it until you fix the obvious errors of x, y and wakelock request".)
If there's no wakelock permission shown for the app, since "release wakelock" could mean anything (the developer didn't write this app for the general made-at-home computer), so only the developer can tell you what it means and what to do about it. If you got it from the Play store (which I hope you did - some sites have apps that are loaded with viruses), tthe developer's email address is down near the bottom of the page. Email them and ask what you should do.
(Developers like this give script kiddies a bad name.)
