I'm having this exact same issue. NOTHING on my computer has changed in the past 2 years. I login, click "Remember Me", it tells me I've used X of 5 attempts, but while on that page I click "Airline Pilot Forums" with the error message displayed, and in the upper right corner it shows a successful login. Everytime I leave the site, it logs me off, and when I go to login the # of attempts keeps going up, 2 of 5, 3 of 5, 4 of 5, etc... What gives? Any clues?
