Same here! I re-installed windows on Dec. 31 and till now I am unprotected (yes, because signatures dating from 18 May 2007 is the same has having no protection at all). I am amazed that ESET continues allowing this to happen, since this has happened every time a larger update comes out. Leaving users without protection for several days is a bad business strategy - it's the second time this has happened to me since I got NOD32 and let me tell you that I don't feel safe! It's like trying my luck at the lottery every time I re-install windows. When the time comes to renew my license I may ponder a more stable product instead - which is a shame, because I really like NOD32 (when it is actually working propperly). By the way: The message NOD displays upon failure is both useless and a lie! How hard is it to replace it with one that doesn't lie to your face, telling you that you are protected when in fact you aren't?
