Anyone still using an XO (from one laptop per child)?

[hobbitbabe]

I'm trying to use mine while my laptop is having problems. I managed to get on the Internet with my new wireless. I can browse webpages. But every site that requires login is telling me that the security certificate is too new!!

My ideas are, maybe this means I need to update the OS, or maybe chck a date setting. Unfortunately I can't figure out how to do either.
