Hey Aron, I had trouble with this too but it is a very simple fix! All you have to do is put the .BSP in a specific file directory.

• Create a folder on your desktop. Name it the name of your map (e.g. rp_downtown_v4c_v2)
  
• Create a folder inside that folder called maps
  
• Insert the bsp into the maps subfolder
  
• Final directory should be: (Mapname)/maps/(mapname).bsp

WHAT!!??!? IT WAS FACEPUNCH!!!

Does anyone know how to make or use Tracers when creating SWEPS
