What happen to me, was that I lost the ability to open any library files. Everything else seem to work, but could not get the library files open. First thing I tried was to copy over the Poser rsr file, which seemed to be the problem, but that didn't work. That's when I just created another Poser file and installed the shobang in it. Then copied the orginal Library files to it. I understand the reasoning behind beta files and programs, but geesh, I think that I will wait for a delta, gamma or even omega in the future
