Hi everybody I own a 2 years AV licence that expires on May 2014. I'm running windows XP Professional 32 bit, SP3. Until recently i had installed a previous version 5 of AV, but my system was freezing when external hard drive was connected. To solve the problem, i uninstalled it and installed the latest version of Nod32 (188.8.131.52), by following all the details written in ESET support pages, but unfortunately didn't solve my problem with the freezing. So, yesterday night i decided to roll back to version 4. I had version 184.108.40.206 saved in my hard drive from previous use (months ago). So, i used this one, without needing to download it from the ESET page again. I uninstalled V220.127.116.11, installed V18.104.22.168, restarted my computer, used my username & password, updated all definitons, upgraded to full version (by updating all modules etc.) and after more than 12 hours still says that is a trial version which expires in 30 days What's wrong and my roll back wasn't successful on validation? Do i have to follow another procedure?
