Try reformatting the USB stick and run the executable. If this does not work any possibilities to test the DSS LITE with another system?
I have the same problem. Internet Explorer,Opera as well as firefox do not work.
I set the time and created a new certificate - but it does not work.
IE complains about a wrong certificate and does not display anything.
The others display a empty pages after accepting the mismatched certificate which is origined from localhost (127.0.0.1).
Maybe a lead to follow up for open-e ...
And what about time settings - maybe certificate is not valid because different time on your desktop and on DSS ?
