Can't unpause a device

I paused 2 devices yesterday and must have inadvertantly paused another machine (a pc laptop) which now will NOT unpause even though the app is showing no unpaused devices. I just keep getting a browser message that i need to unpause in the app. I've tried clearing cach, restarting, rebooting router...nothing works to unpause this computer. None of the forum postings have showed a solution even though there are dozens of people submitting the exact same issue. How do i unpause when nothing is showing paused?
