I've had this problem for quite a while a now, and I'm not sure what to do to fix it. It all started a while back, I say a month or so, Cydia just decided to stop working. I'd press Cydia, it'd open, then close, without even saying an error, or "Loading data". I've looked into this and have tried pretty much everything. I've uninstalled and reinstalled Cydia through Mobile Terminal, I've restored TWICE, reinstalling through Rock, but nothing works. I've given up, so now I'm coming here for help. Any suggestions?
