What version of safestrap are you using? It seems to me that you are on a older version. Get the latest safestrap (version 1.0.9) and then do the usual full wipe, cache, dalvik, format system and then install. I am sure that should work for you.
Oh goodness didn't even see that I was still on an old version!! Thanks for your help I'm about to download the new one and give it a try
