[W3D Launcher not doing anything]

I updated the launcher but its saying I need a serial number. I bought it off Origin how would i find the serial number?

 

Also its saying I need Windows XP Service Pack 3 or greater?

 

[W3D Launcher not doing anything]

I downloaded W3D launcher and I have renegade from Origins. When I run the launcher it just prompts me to pull up origins and open Renegade through there. I obviously dont remember my login and password from ages ago. I thought this was just supposed to Direct Connect me instead of bringing me through Renegades menus?
