I have the trial of MOZ right now but the open site explorer hasn't updated since Dec 4th

What do you do to get the lasted information?

Ray is correct our next index is scheduled for this week (Jan 28th).

CJ5 - I apologize for the delays we've been seeing with our index, and please know we'd love to get you fresh data ASAP. We had some unforeseen issues early in January that led to this delay. We are working our hardest to get you complete, fresh, relevant link metrics. I do apologize for any issues you have in the meantime!

If you're looking for fresher results, try the Fresh Web Explorer tool (http://freshwebexplorer.moz.com/).  Open Site Explorer derives most of it's value from looking at the history of a website: cumulative links, what goes into getting a site it's domain authority, domain trust, etc.  It's very useful for digging into how 3 or 4 competitors got to where they are now, and areas that you could target as well. That being the case its index update isn't as mission critical.

If you're trying to find information on your own site and it's brand new, you'll probably be better served by using the webmaster tools available at the engines for the first month or so. Can you expand on what type of results you're trying to achieve with the OSE and maybe I could give you more specific guidance or alternate methods / tools.  Cheers!

Like Ray said, Moz has been slow in updating the index. I'm a subscriber and I'm getting quite disappointed by this. The December index was delayed from when they initially said it would be, and then this January index has now been delayed twice. Just FYI.

The Moz index is usually refreshed once a month, however, it's been longer than that since the last update this time around. Moz has a big index update schedule for the 28th, I believe.
