Is anyone else seeing an "Security Information" warning message when using the the DT Java upload application?

Mine asks: "Do you want to run this application?"
It goes on to say: "This application will run with unrestricted access which may put your computer and personal information at risk.  Run this application only if you trut the publisher."

Further info says:  The application's digital signature has expired.

I did not upload. 

That hasn't worked for me in so long I cant remember when it stopped working!

I can and do only upload using FTP with Filezilla.

And they still give funky rejection reasons anyhow.
