Jnan,
I think your question is being interpreted that you are trying to access your Aloha EDC through the "super user" key sequence that dealers have used historically to have complete access to the system and allow for things like changing processor information.
If you are logging into EDC and Stopping POS Processing and you do not have the access allowing you to alter, add or delete processor information then whatever login/pw you're using does not have access to those functions and you need to try to use the "Super User" login to make those changes.
Shoot from the hip
