Open Microscopy Environment

I am trying to import EVOTEC flex files into ImageJ using the LOCI package, the metadata appear to be read correctly, but the image import doesn't work. Ironically, in imageJ without the LOCI packages, the images are visible, but the metadata cannot be read. The error that is seen is a Java NPE. The same issue appears on both Windows and Mac. Can anyone help?

ImageJ 1.47v; Java 1.6.0_51 [64-bit]; Mac OS X 10.8.5; 52MB of 658MB (7%)
java.lang.NullPointerException
