Near-identical code causes errors?

Question

So I have 2 lines of extremely similar code. Here is the first line (which has no problems):

Player.Tex = Content.Load<Texture2D>(@"Textures\d");

And here is the second line (which has a TypeInitializationException)

HealthPickup.Tex = Content.Load<Texture2D>(@"Textures\healthPickup");

In the Player class and the HealthPickup class there is a line just after public class with this:

public static Texture2D Tex;

So why is my HealthPickup class causing this error? Have I missed something obvious? I have tried searching for the exception but nothing helps.

EDIT: As requested, my HealthPickup class is as follows:

Also, my Player class:

Notice that my HealthPickup class is identical to my Player class apart from 4 variables, (Tex, Dir, Pos and speed in Player and Tex, randX, randY, Pos in HealthPickup)

You are trying to convert an object of type Random to an integer. This is not allowed. You can get a random number from Random object using one of the Next method overloads. Like so :

(new Random (Guid.NewGuid().GetHashCode())).Next()

using Guid.NewGuid()... is not obligatory, but will make sure you get 2 Random objects with different seeds
