Hi tech232 :-)
Try the following and see if it helps:
First: It is very important that the time of your computer clock is correct.
Every Certificate has an expiration and start date. When your machine clock
time or date is off, even just a few minutes or hours, it may cause the
Certificates to be seen as invalid or expired, which can cause various
problems. So, be sure your machine date and time are always set correctly.
If still no joy....
Go to IE>Tools>Internet Options>Advanced
Scroll down to the Security Section
Check "Allow software to run or install even if the signature is invalid"
UNCheck the following
"Check for publisher's certificate revocation"
"Warn about invalid site certificates"
If that does not work, you might also try:
Go to Tools>Internet Options>Security tab>highlight Internet
Click Custom level tab>scroll down and Uncheck "Don't prompt for
client certificate selection when no certificates or only one certificate
exists."
also..
