When an image file is added to a new or existing model as a background, the product crashes without an error message.
After loading the image file as a new background, the Image Properties dialog will open. Uncheck the box for "Use Compression" before adding the background file. This should resolve the issue. This issue will be resolved in a future release of the product. The reference number for this 1087621.
If the image file is a screenshot of an aerial photograph near the network you are modeling, the best solution would be to use the Bing Maps feature instead.
