Noona writes ".. but why all of the sudden? It worked fine for years .." I am running up against the exact same thing (same message etc). I have not downloaded squat for years - no updates to Poser, no new system software, no "Flash" updates. Stuff happens, and if it was just me I would assume this Mac was just getting old (which is the case). However, the consistency among different users suggests someone (Smith Microsystems?) reached into my computer without my permission and did something to prevent me from using Poser 9 so that I would have to shell out $100 for the update to version 11 or lose the art I have generated over the last several years. Am I missing something? How many people are dealing with this BS?
