Jumbled file names

In the directory tree all my files and folders are named perfectly. In the viewing panes they are all jumbled and shortened with tildes. I ran as administrator which seemed to make it run correctly but then it began again a short while later. I have UAC off - but I don't know if this is connected. Any help will be much appreciated.

This is known to happen with some pirate versions. If you're not using one of those, please contact GPSoftware support for assistance.
