Why am I not able to use user-created weldment profiles saved in 2015 release? 2014 user-created profiles that were not over-written or created by 2015 release work fine.

Just upgraded to 2015 from 2015 early release. I now get the message that the "Library Feature is Empty". when trying to use Weldment profiles created with the new 2015 version. I made the mistake of over-writing another user-created profile and now that one doesn't work either.
