gypsymoth,
This is not a problem with your Cascades install.
Look in the ..\Scenery\World\texture\.. folder for the '033b2su7.bmp' file. If the file size is 33kb then this is the problem.
The file is installed by Silver Wings and was mistakenly saved without MIPS. The fix is to open the file in DXTBmp or Image Tool and resave with MIPS included.
You can download DXTBmp here-
http://www.btinternet.com/~mnwright/programs/dxtbmp.htmIf you haven't worked with DXTBmp: Open the file in DXTBmp. On the right side of the program screen find the MIPS section. Put a check mark in 'Include when saving'. Save the file. It should save in DXT 1 format, and the new file size should be 43kb.
If you prefer, I can e-mail the file.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
