I keep getting this: NET::ERR_CERT_DATE_INVALID using Chrome and some web pages won't load [other pages do load], IExplore won't access these pages also. I found the certificate for the: DST Root CA X3 has expired. Investigating, I found a reference to: 48504E974C0DAC5B5CD476C8202274B24C8C7172. I run Windows 7 64 bit and found teh SystemCertificates locations in the registry. How do I remove this old certificate and replace with the proper one? Thank You, Dennis Nichols.
