Mingdao application can not update the SSL certificate, how to do it, can't use the solution

Can't update the SSL certificate and can't use the following three solutions: 1. Using Firefox browser, 5 cases are found, can solve 2, update the operating system. Use Windows 7 or higher system 3. Please check if the computer date setting is correct. If the setting error will also cause the certificate to be invalid, the second option is recommended. The reasons are as follows: 1. Microsoft will not be Windows XP from April 8, 2014. Provide support and updates. This means that using XP will be very insecure and inconvenient. 2, the reason why it appears in the XP system, because XP released several patches this year, there are changes to the security rules of the SSL certificate, if you use the last year's SSL certificate is no problem, but there is a problem with the new certificate (But Microsoft has not fixed this problem, please see the first one for reasons).
