today I have changed some Parameters in the Default Profile of my SAP ABAP 7.52 trial server.
After the changes, i can't login to the SAP System anymore, Errror is "Connection refused".
What can i do to rollback profile changes on the server? Deleting the new Version of Default Profile did not resolve this Issue.
Apart from that I changed nothing in System Configuration.
PS: No Backup of Server exists, i know i know....
