Hello, I have a certain program on my PC that will expire soon. To avoid this, for I still need it for a few months, I have changed my computer's date to a previous one. But now the problem is that I cannot open certain sites in any browser (except Internet Explorer - but that browser doesn't work correctly from other perspectives). All I get is either blank pages, either the message UNTRUSTED SITE. My question is: how to null/delete/stop the web browser from checking my system's date? (This problem persists with Opera and Google Chrome too)
