When i click sources then edit and add cydia freezes and no gui ever pops up! HELP

[Erer1243]

So I open Cydia and click Manage--> Sources--> Edit--> Add, The add button never goes dark and cydia Completly freezes until i exit with home button! Im not big on cydia stuff yet so im not sure what to do!! I cant add ANY sources! PLZ HELP *Update* It seems to have fixed itself :/ but i think i know why (it ran out of battery and turned off when i left for a few days, i have a tethered jailbreak [Which sucks] and i have been trying to keep it on)

Sounds more like a software issue rather then a Cydia issue. A restore and re-jailbreak may be your only answer to cure it>
Is this something that just started happening, what did you install last or what repo did you install last? Might try deleting recent changes/additions also to see if that caused the conflict.

Also, what firmware and what jb did you use.
