Ok folks we've just released version 0.12.2 which is a bug fix update. If you were having trouble running NMM before, please try now.
NMM should inform you if there's a new version when you run it, and offer to download and install it as well (saves you going to a specific page for every update).
If you have installed NMM and it crashes before allowing you to auto-update please go to http://tesnexus.com/content/modmanager/ and use the download button. No need to uninstall your current copy, just go through the setup process again and you'll get the latest version.
I'd also like to say a big thank you to everyone who has used our http://www.thenexusforums.com/index.php?/tracker/project-3-mod-manager-open-beta/. Not only that you've bothered to use it, but that you've all provided exactly the feedback and log files we've needed. It makes a tremendous difference when the bug reports we get have exactly what we need to tell us what's wrong so we can fix it. So a big thank you again
