question about the addon to use

hi I am an affliction warlock and recently I download the addon for dps that i think is called skada. for no reason it stops working maybe you could help me.
I also need help to know which addon/macros I need to use as an affliction warlock because my dps is not satisfactory so I start thinking that I am making some mistakes

for "skada" issue, you need an addon like this: https://www.wowinterface.com/downloa...6001-r20100217

for warlock's guide/macros there is a class section: http://forum.warmane.com/forumdisplay.php?f=128
