Getting this error - how to even get the instance up again?

Hi Chetan,

ACS Error should not be an issue [A].  However the error "AuthenticationSupport service missing"  indicates repository is not up.

• Check the permissions of file system crx-quickstart/repository.   If it is read only to folder change it to 755.
• By taking backup of instance Delete the last line entry at crx-quickstart/repository/segmentstore/journal.log and restart the instance.
