The security certs apparently have activation dates in the future rather than current ones. Error code SEC_ERROR_OCSP_FUTURE_RESPONSE Afraid I'm running Windows XP...Please help!

First thing to check is making sure your system date/time is correct on your WinXP OS.

Thanks very much for your help. Yes it was the clock, somehow it had got turned back exactly one month, which I didn't notice at first, as the day and time were right...I'm wondering if it was a virus. Thanks again
