Hi, this has happened to me now too. Worked fine when I first installed it yesterday (with permalinks as /%post_id%/%postname%/). Had to sort out another issue so disabled and re-enabled all the plugins and now liveblog only works with the default ?p=xxx permalinks. Very strange. Even on the same test live blog page I created yesterday. I tried installing the Git version zip as well but that didn’t solve the problem. Some strange combination of deactivating Liveblog & W3 Total Cache and reactivating them did. Now seems to be working again with permalinks in place. Weird.
