First, I'd like to note that the link on your page to buy OVA is wrong. It' currently leads to a Star Trek book. The correct link appears to be this:
http://www.rpgnow.com/product_info.php? ... ers_id=639

With that out of the way ...

I've got the print version of OVA... it appears as though there's an errata file that can be downloaded, does that cover me for everything? It seems like there was an updated pdf made but it never got uploaded?

The game looks interesting, and I'm hoping to be able to run it in the near future.

Your copy of OVA should be fairly up to date. Only a few minor changes were made after the latest print run, and those are, as you expect, detailed in the errata.

And yes, I know the link is wrong. RPGNow recently merged with Drivethru RPG...The result being all old links get royally screwed.

As of late, I've been to busy, but I plan to give the site a major working over. It's outdated in more ways than just that link, I'm afraid.
