So i'm trying to open the american airlines website and at first it opened fine but now it doesn't load (It just stays blank) and it shows the SSL thing saying that the certificate is not secure. Worst is that after this happened with google chrome it tried to open it with IE and at first it opened but now it doesn't work with IE i don't know what to do and I need to buy airline tickets asap (by tomorrow) PLEASE HELP!!!!!!!!!!
