Invalid Server Certificate - Unable to Proceed

[Onyx50]

Howdy Forum! Hoping someone can help with the following weirdness:

We just started receiving the Invalid Server Certificate warning and we are unable to proceed.
The only choice we have is the "Back" button. There is also the "Help me understand" link.

Just started receiving this last night and it is happening on every system. Please note the following info:

1. Only happening with https // Startpage.com (that we know of).
2. Verified that it is not malware related. Systems are totally clean.
3. Not happening with Firefox, Seamonkey or Opera - only Iron 21.0.1200.0 (Developer Build 151001 Windows)*
4. Using XP Pro
5. Emailed startpage support - awaiting a response.

* Yes, we realize this is an old version of Iron, but why all of a sudden this started and on every browser?
We've checked startpage's certificate and it appears to be ok, is there any way to circumvent this warning screen within Iron?

Checked all over the web for answer but unable to find anything helpful.

Thanks in advance for any help and\or ideas for this problem!

Yeah I'm having the same issues.

The only way to over ride this is when you do get the message, then type on your keyboard "proceed" and hopefully let you get to the site.
