Torque X Particle Emitter Issues

Hello everyone. I just bought Torque X and I am loving it. I am having trouble with the 2D particle effects though. In the TXB, the particles show up with correct blending. They are png files with transparency and when viewing the particles in the builder, they blend right in with the background. When I actually play the game though, you can clearly see the edges of the particle texture. Why is this the case? Also, the texture is much lighter when I am playing the game than when I am viewing it in the Torque X Builder. Please help me with this.

Thanks
