It appears you have deactivated your alerts. This probably occurred when you clicked the checkbox that said "Prevent this page from creating additional dialogs".

Because the alerts have been disabled, your confirmation action cannot be captured and we cannot proceed with this process.
To clear this issue and get you on your way, it will be necessary to (1) log-off, (2) log back in, and (3) return to this process. In some cases, it may be necessary to completely close this Internet browser and other related windows after you logoff to fully clear the setting.
When presented in the future with an alert, please do not click the "Prevent this page from creating additional dialogs" checkbox, as the situation will repeat.
Thank you!
