can anyone help me with this? w/screen pic

[muddyape]

Added a repository (overloadnetwork.com?) because it came recommended but this screen pops up when i enter Cydia. It is annoying and nothing I want anything to do with any longer. Is there a way or section to access and delete this repository that seems to not have downloaded in its entirety? It is not in packages or sources in cydia. I know more about this phone (3gs, 4.0 with Comex' jailbreak) then I want to but nothing compared to those here. A little help please.

Download Cyfix GUI and remove link or manually enter phone via SSH to remove unwanted Cydia repos.
