Application loader problem?

Hi.
Keep getting the following error when starting application loader on my mac.
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “contentdelivery.itunes.apple.com” which could put your confidential information at risk.
anyone have any idea's what the problem could be..... app finished and just trying to upload to store....

Make sure you have the most current version of loader. You can find it in iTunes connect as link.

HELP......
just to mention have downloaded and installed the lastest application loader from iTunes connect...
Would it be an idea to revoke all my certificates and profiles and start from scratch? or would this not be possible.?it just seems when viewing the background activity when adding application the only part that fails when verifying metadata., everything else is ok.
