Just one remark.

If you have multiple runtimes (if you don't try it out, it's a real bonus) you may have to reattach those runtimes but everything will appear as it was before after a restore. You may consider copying your entire Poser directory (this would also restore your preferences). You will still have to install Poser before restoring your directory since some registry entries are only set during the install (this applies to most programs, install first then restore the copy).
