Error with New Ctools Release

Hi all,

I just downloaded and installed the latest Ctools release and get the following error when I open CDE. Has anyone else seen this / known what the problem is?

java.lang.NoClassDefFoundError: Could not initialize class pt.webdetails.cdf.dd.FsPluginResourceLocations

Thanks,
James
