ok, I reloaded my external runtimes.  I browsed each runtime library and category (figure, pose,...) after each load.  The ? all eventually turned to numbers and the content is available.  I don't know why the ? never turned before.  I once gave it 24 hours.  Maybe it had to do with something particular to whatever made P8 crash when I removed the library named 2009.  That library also works now that it has been reloaded.
