I downloaded some recourses yesterday that got updated. After installing them Logos started to index. Indexing stopped at 18% (the blue Logos icon disappeared in the task bar, but the yellow bar was still showing in Logos, remaining at 18%). I restarted Logos. This time it made it to 4%. I left it all night long with now results.
I'm using Logos 5.2b SR-2 on a Mac OSX 9.4
