Companion problems

The companion suddenly started throwing this error last night: Attempt to invoke virtual method 'java.lang.String java.lang.Throwable.toString()' on a null object reference. I'm using version 2.70 and it seems like the reason for this error has been an out of date companion. @Akhil_Muraleedharan had a post about this. Is there a newer version?
