You need to wipe with Jl_cmdr (see the FAQ) and then reload the OS. That should fix it. The security wipe must have left some files from an app or theme that you had installed.
Plus that type of error is difficult to find as it is generally caused by an incompatible app or theme or a corrupt file(s).
Google is your friend. Maybe this will help. If not Google the error and see what you find.
