Try removing the battery for 10 minutes. Press and hold the Enter button for 60 seconds to fully dissipate power in the unit. Re-insert the battery. Then power it up. If that doesn't work, contact your Credit Card Processing Company and tell them you need a new one.

That message can mean many things including:
* The organization issues their own certificates, and they're not a recognized CA (Certificate Authority)
* It's a subsidiary company using the Parent Company's certificate -or vice-versa
* The certificate has been revoked
* or been corrupted
It depends on the company and what the certificate says as to whether you trust it.
You should be fine if u know the site is trusted your fine. I get the same with Google sometimes I think it has nothing to do with devices but on there end maybe server issues but I wouldn't worry. Yes it's annoying but mine just stopped so you might have to do the same and just wait
you will most likely need to get a new signed certificate from the vendor, the certificates are used for secure transmission between the card processing company and you. Give them a call, they should be able to issue you a new cert and get you going again.
Most security certificate are valid for a year or two. If you computer's data is out of that range it will assume the certificate has expired or hasn't yet become valid. The first thing to do whenever you have certificate errors especially on secure websites is to check the clock.
Right click the clock and click adjust time/date and make sure the Time.....the Day....the Month and the Year are all correct....and finally check you are in the right time Zone. While in Internet Explorer, click "Tools" > Internet Options > Advanced. Scroll down to the "Security" section and uncheck the "Check for publisher's certificate revocation" box.
Outlook express has a setting to check for certificate revocation. Drop down the Tools menu and choose Options. Click on the security tab and on the Advanced button.
You should see a section towards the bottom of the dialog box named Certificate Revocation.
I have never changed these settings and mine is set to Never.
If yours isn't set to never give it a try and see what happens.
Digital Certificates are used for encryption and authentication.
Revocation is used when a Certification Authority issues a certificate to a company or individual and then something happens that makes the Authority cancel the certificate. There are many reasons why and I'm not going to speculate.
Have a look in your case who issued the certificate and who it is issued to. It could be someone up to no good and you would be better off to figure out what is going on before you just turn it off.
