My thanks to you!!! I did what you described, and my program is running fine.
I have been using Generations Beginners 8 for about 4 years, and same computer for well over a year, and just today, I started having the "disappearing" problem.
After using the method you described, it turns out that the problem was one of the files that I installed for my new printer.I disabled it in start up, and as you said, everything is still running fine.
Thanks so much!(I was sooo close to total panic!).
