In this case, I'd say the same as all the first-line (rabbit) tech support people do - 'have you closed and restarted your program? Have you rebooted your computer?'
('rabbit' is a 'get there quick' technician; service contracts usually have a minimum response time in them - one pays more for shorter time [extreme version is a tech that lives at your site 24/7]. Doesn't matter to the contract terms if the person who shows up can't fix the problem, some body showed up to meet the response time.)
