The CORE Generator application may hang during startup if a directory
corresponding to a previously existing project has been manually deleted.

Next, edit the known.prj file located in $XILINX/coregen/preferences and
remove the line referencing the deleted project. Save the file, then
restart the CORE Generator application.
