This is most often caused by an incorrect or corrupt Microsoft Silverlight install. Silverlight is a framework which Microsoft's Bing mapping service requires, so Street Maps requires it as well. Take the following steps to re-install Appraise-It and Silverlight.

Manual
1. Perform a clean reinstall of Appraise-It.
2. Open your list of installed software.
3. Once the list of software installed on your computer populates, scroll down and find Microsoft Silverlight. Uninstall it. (If there is more than one, uninstall them all.)
4. Go to the Microsoft Silverlight website and click Install Silverlight, then follow the download and installation prompts (click Run or Yes or OK or Allow, et cetera, when prompted).
5. After the Silverlight installation is complete, return to Appraise-It and attempt to open Street Maps.
If Street Maps now opens and runs correctly, your problem has been resolved. If you are still receiving errors, please contact Technical Support for further assistance.
