Hi, I have za for a few years, and with some small problems, that I solved, I am very satisfied. But now I received update alert, and when I downloaded it just erased za from my system and now I cant install it any more. Installation started and then just completely stop and nothing is going on. I used nod32 to check the computer and he found, beside za.exe installation program on my desktop, he also found some unknown treat. Of course I deleted the treat, and after that happened what I described up above. anybody know what to do, before I reinstall my Windows. Thanks.
