I downloaded new ZSZC client 1.79 and updated it to 1.80. If I choose server and hit "Start". Launcher goes off(thats normal) and I get this: "sro_client.exe has stopped working". What"s wrong?

I have windows >>VISTA<<

And another thing. I have Csro installed, but I only extracted and patched ZSZC (wich means I have csro registry files registered)
Can this affect ZSZC?
