Well, I found out how to delete the preferences and all, but the location the instructions sent me to only had the Library prefs xml. I copied that to my desktop, just in case, and deleted it. Started Poser again, but no luck. It still will not open. I noticed that the windows dialogue box had a button for more details on this, so I opened it and copied what was there. But have no clue what is happening and not sure if anyone here would either, but here is what it had:
