iPod touch Cydia not Opening

I've had my ipod touch 2g jailbroken for months now, but recently went into cydia, and it started updating itself, and then closed and will not successfully open anymore. I searched and found that this can be easily fixed by either using ifile, or a combination of sbsettings and ssh-ing. I dont have ifile anymore and have not set up my ipod to work with ssh. Is there any other ways that i can fix cydia?
