Bad Juju

Don't know what it is, but I came to work this morning, and my office equipment is boycotting me. ALL of it. My PC wont connect to my Mac, or the net. My Mac wont run the diagnostic programs I want it to, the DVD Duplicator (which is ususally rock solid) has had to be restarted twice, and created 11 coasters at once. ( The previous 900 copies had no coasters.) The DVD printer, despite saying full on ink, is refusing to print a decent label on my discs. And running the "Clean cartridge" utility 3 times hasnt fixed the situation at all. It's going to be a tough day at work today...
