Thank you all so much for your help, and especially to Peter who went to the trouble of actually trying to duplicate my problem! I tried the various suggestions and finally gave up and hired someone from elance.com to solve the problem, which he was able to do. So now my blog is up and running well.
I really appreciate all the suggestions you all have made, and for taking the time to consider my problem and to think about what might help.
Thank you, Thank you for helping me to get up and running on wordpress!
