I was on step 59, and I hit enter before finishing step 62. It then took me to another page that I can't remember so I backspaced to continue step 62. since to original label was blank I re-entered "Meeting" and steps through 64. Now it says that Error invalid data that name is chosen. What can I do without having to start all over again?

Ok, so yeah, the error message says you have to enter a value for Label, which should be "Meeting" so enter "Meeting" into that slot as directed in Step 75 and continue with the rest of the steps, 58, 59 and so on, ok?
