A little while ago I changed how the autogen configuration is read into scenProc. This change resulted in some unexpected crashes for some users. These seemed to happen mainly when FSX was installed within the Program Files folder and Windows did not give the right permission to read the files.
I have now made the code to read the configuration more robust and also worked around these permission issues. So if you download the current version these issues should be fixed. So if you downloaded scenProc in the last week or two, please update to the latest version to save yourself some trouble.
