I have been using InDesing CS5 for about 3 or so years now, for work. Just recently, I have begun having some problems where I try to open the program and it hangs, and I have to force quit. I experienced this about a week ago, and after looking at some other forums I tried resetting the preferences and deleting the SING plug-in, based on suggestions for similar problems. It seemed to be working again, where I could open up files and work on them fine - but now, it is doing the same thing again. Every time I try to open a file, or even just the program, and hangs and I have to force quit.
