On the Australian website today, they are advertising and selling ESS 5 not 6, yet I can't seem to see any reason for this..... Oh maybe all the freezes and crashes I have been experiencing has something to do with it.....
May be a problem from the Webmaster ;-) Simply chose the Free Trial and you will see that Version 6 is installed - just tested it for you ;-) By the way on Win8 X64 Eset is stable enough to secure a pc.
