I had 2 HD burn outs last year and luckily I had back-ups.
I did it in a similar way to markschum,

I did a clean install of Poser, deleted the Runtime and replaced it with my back-up runtime, worked no problem, no loss od anything and back running in a coupla hours instaed of days or weks trying to reinstall stuff manually!

Injustice will be avenged.
