Hi, so i'm having a bug with the addon, gmod says that it's a lua error, those are the errors:
[Portal Gun - Enhanced Aperture Science Handheld Portal Device] bad argument #4 to CreateConVar (string expected, got bool)
1. unknown - lua/entities/projectile_portal_ball/shared.lua:15

[Portal Gun - Enhanced Aperture Science Handheld Portal Device] bad argument #4 to CreateConVar (string expected, got bool)

[Portal Gun - Enhanced Aperture Science Handheld Portal Device] bad argument #4 to CreateConVar (string expected, got bool)
1. unknown - lua/entities/projectile_portal_ball_pbody/shared.lua:15

Yep, those are 6 errors.
Note: idk if it's another mod creating those errors, but the only thing i know is that other textures are missing, like the physics gun texture.
Bye!
