Seems like a simple reboot brought all my systems back on-line. Don't know what may have caused it to go haywire, and I was a tad worried about any virous's being streamed through. Nothing bad seems to have happened.
My apologies to jain; there were no serious consequences, but I wanted to ensure that nobody else may have gotten affected.
So, the pluses just got better! I now have a set of parts manuals! Hope it's a very, very, long time before I need use them for repairs, but I'm the kind of guy that likes to have any useful resources available at all times.
