Maurosh,

There has been a similar incident, I believe.
Start reading here , to see how strange a wall with texture can behave.

Known causes of problems are:
- too large textures (over 1024x1024 pixels)
- too large files
- certain DAE/Collada files, especially low-poly models
- too many textures
- not enough memory

At www.mediafire.com you can upload large files. Downloading is not a problem.
