I'm making a solar system and for some reson it won't work. (Get the textures from 3dcafe.com)
AppTitle "Solar System Sim"

Graphics3D 1280,1024,32,0

SetBuffer BackBuffer()

camera = CreateCamera()
light = CreateLight()

Sun = CreateSphere()
Mercury = CreateSphere(10,Sun)

Yellow = CreateBrush(255,255,0)
tex = LoadTexture("Mercury.bmp")
brush = CreateBrush()

BrushTexture brush,tex
PaintMesh Mercury,brush
FreeTexture tex
FreeBrush brush
PositionEntity Sun,0,0,0
PaintMesh Sun,Yellow
FreeBrush Yellow

While Not KeyHit(1)

RotateMesh Sun,0,5,0

RenderWorld
Flip

Wend

End

The camera is not positioned, so it starts at 0,0,0 - effectively inside the sun. When you run your code all you can see is a black screen. Try putting "PositionEntity camera,0,0,-10" below the CreateCamera line, so you can at least see something happening.

It says "Could not load: Mercury.bmp" Here is the new version:
AppTitle "Solar System Sim"

Graphics3D 1280,1024,32,0

SetBuffer BackBuffer()

Global camera = CreateCamera()
PositionEntity camera,0,0,-10
Global light = CreateLight()

Global Sun = CreateSphere()
Global Mercury = CreateSphere(10,Sun)

Global Yellow = CreateBrush(255,255,0)

DoLoadBrush(Mercury,"Mercury.bmp")

PositionEntity Sun,0,0,0
PaintMesh Sun,Yellow
FreeBrush Yellow

While Not KeyHit(1)

RotateMesh Sun,0,5,0

UpdateWorld
RenderWorld
Flip

End

Function DoLoadBrush(mesh,what$)

If FileType(what$) = 0 Then
	brush = LoadBrush(what$)
	If brush = 0 Then
		RuntimeError "Could not load: " + what$
	EndIf
Else
	RuntimeError what$ + " does not exist"
EndIf

PaintMesh mesh,brush
FreeBrush brush

End Function
