Sometimes the runtime system files that TwoDog relies on do not install correctly. We're not sure exactly what causes this (it seems to happen 1 out of 20 to 30 times) but luckily it's a very easy fix. All you need to do is re-run the either the full installation file, or you can grab and run just the part that deals with the runtime system files.
If you don't already have the full install handy, we recommend doing the 'system files only' just because it's a smaller download and simpler process.
