When starting the game the loadout does not spawn, the view model is set to the HL2 player model, and an error screen blocks the screen.

When I spawn a weapon the error goes away and I can still select a view model. It's just that every new game results in this problem. Otherwise I love the mod and wish I could use it on my server.

Mods that come to mind that might be conflicting:

WeaponSets- Weapon Loadouts
Enhanced PlayerModel Selector
