Have been using GS7 ok for some weeks now on El Capitan
Trying to fill in the upgrade details for moving from 6 to 7 today in GarageSale but I cannot get past the validation area where it states that my email address in not valid.
I have been using this email address for 2 years. Tried all my older addresses but the same issue.
Because of this I cannot even to GS to list items. I do not want to be stuck over the weekend.
