I don't know what -1 is.
And, yes, the clock is accurate. Its synchronized with windows.time.com or something like that.
Next, make sure your browser is allowing cookies from NG
I'm pretty sure it is, my settings say 'Allow sites to set cookies', so i guess it is.
Failing that, close your browser, clean your cache, and start up a new browser.
Its been going for weeks. I've cleared the history, cleared the cache, restarted in 2 other browers and nothing works.
Help :)
