Murphy's Law was in effect for this problem. I moved my latop to a different surface, (put it on a large heavy plastic t.v. tray type table) that I use sometimes when setting in my comfortable chair to work on my laptop, away from the heavy, and I might add, very level desk that it is usually on and the Microsoft Office Home and Student 2007 loaded without a problem.
I am guessing that only for that DVD that the moons (literally) were not aligned properly. So try a different surface before taking your laptop into the shop because only one DVD won't load
Weird isn't it?
Thanks to everyone for your help! Anyone ever have a Murphy's Law problem before?
