Yes, i got the same issue with an unlikely file.. My Antivirus "Warned" me that Tequila was about to download a "suspicious" Physxloader64.dll, which it got blocked.. Ironically, after re-validating through Tequila, everything seems to be in order.. I did try the 64bit client too, and works just like the 32bit one, even though the loading times are slightly shorter..
My ping was higher than normal, but hey, it's Justin, and i'm on the EU.. 😆
