what happened to your pc?don't download the standalone, you're a lot safer and better off using the regular site. trust me on that. while i had the standalone, it caused a lot of freaky shit to happen and it constantly made me lag and changes kept being made to my computer. don't download that shit. i'm pretty sure it's not an actual professional client.
e; just to add on, but the same thing happened to a few others i knew awhile back. i wouldn't be surprised if sevenops was doing some illegal shit without us knowing.
