OpenSUSE :: Removing A Repo - Error "can't Find The Data For The 'problem' Repo"

I wasn't paying proper attention when adding a repo to yast and need to find the file were the info is saved to delete this. The problem is that whenever i use yast it comes up with an error code saying that it can't find the data for the 'problem' repo. Have tried zypper rm but that comes up with a similar error advising that the data is in a format that was not expected. My thinking is to track the file were the yast repo source details are saved, delete this and then just add the repos that i use back.
