Spring board crashing after installing new theme.

The theme was called animated snow. It added animated snow to the lock screen like the name suggests. after installing spring board kept crashing and going into safe mode. so I disabled the theme and uninstalled and it kept happening, so then I reinstalled winterboard and it is still happening. Does anyone know how to fix this? (hopefully w/o rejailbrakeing). Goddamn it, I love my jailbroken iphone, and this is the first trouble I have had with it. I guess I learned my lesson about installing random shit.
