Troubleshooting
~~~~~~~~~~~~~~~
In case you experience any problems, try to delete all these files from your disk and then start over:
 - Virtualtrees.*
 - VTAccessibility.* 
 - VTHeaderPopup.*
 - VirtualTreesD.* 
 - VirtualTreesR.*
I recommand using UltraSearch for this task: http://www.jam-software.de/ultrasearch/
