L3DT Viewer v2 fails to display terrain-Does not respond

[3DUser]

I'm using L3DT 2.4b on a Gateway PC with 1 GB RAM and 3 Ghz processor and an ATI graphics card.
I'm able to construct a terrain, however, I'm unable to view it.
The L3DT Viewer v2 hangs up. The window opens and is blank. The cursor does not show inside the window. Eventually, I get a message that it is not responding.
Is there a setting somewhere that I should change or is there another solution?

Hi 3DUser,

My guess would be a format problem:

or:

Which formats are you using, and what map size are you using (heightfield and texture)?

Cheers,
Aaron.

I was trying to view a .mgf or a .proj file. That was it. Since I'm a new user, I will go back and review what I did.

Follow-up
I can go to File -> Save ->Save All. Heightfield, Design Map, Attributes Map, and Texture Map all have checks by them. When I go to open in L3DTVi2, only the .mgf format is available for opening. What am I doing wrong this time?

Reloaded the software and it works now.
