Reseller accounts no longer listed via system settings -> reseller accounts

Hi guys, it appears that my reseller accounts are no longer listed when looking at 'System Settings -> Reseller Accounts' as a valid account via the web interface. Looking at the map.reseller file, the name/account is there, but the interface says none have been added yet. I only have one reseller account, and he uses it sparingly so I have no reference for when it actually broke. Would appreciate any assistance in resolving this.

thanks
