Question not solved - no

answer given

Only you can mark a question solved. No one else can.

There is no way to get a question answered in one minute here.

This is not a chat service. This is a user to user technical support forum and Apple does not participate here. To receive assistance here, you need to type out a question describing your problem and any troubleshooting steps you have taken to fix it, and wait for one of the volunteer users to read it and one to answer it.

Read this, Writing an Effective Apple Support Question and then come back with a question meeting that criteria.
