Hi, It seems that there's still a problem with the trial version. In the last few days, I tried to update my trial version of nod32 v4 but each time the update fails : I should enter a username and a password (I still have 20 days...). Most of the time, files are being loaded, it stops and a box pops up asking for UN and PW. I tried everything and read previous posts. I uninstalled and reinstalled the trial version, cleaned hidden folders or even remaining reg entries. Even after a fresh OS install, the problem persists (note that it works with the previous nod32 v3). I guess that the problem comes from eset's servers. Any idea ?
