We are currently working very hard to get the release of v0.6.8 out the door as we discussed a few days ago.  This is a very high priority for us as there are issues with 0.6.6 (the currently available release) running on Windows 7.  A recent update from Microsoft has changed the way some automation features work and this has had an impact on SampleSort.  We have already implemented a fix for this which is included in the v0.6.8 release which will be available on this site hopefully later today!
