More of an enhancement, actually, with additional plugins, extra features, etc. 2. No, it's a part of Poser and installs on top of it. You can, however, install a separate copy of the original Poser in a different directory. 3. Installing the Pro Pack will not wipe out your existing pz3's and other stuff in your Runtime folder. In fact, it'll add some new stuff. Better safe than sorry, though; always back up vital files before trying something new. 4. Poser enhanced with the Pro Pack has about the same system requirements as regular Poser. As far as performance and stability go, people seem to be of mixed opinions. 5. The file formats are mostly the same. Pro Pack adds some additional formats (compressed files), but will read and save the old stuff, too. One gotcha to watch for is that Pro Pack uses .png files for thumbnails, instead of .rsr files (it'll convert your existing .rsr's). Another gotcha is that Pro Pack will no longer convert bump maps to .bum format (although it still reads them). 6. Well, there is some stuff at the CL site. Look here. 7. You can just go ahead and install Service Pack 3. It incorporates all of the updates and fixes in the previous two.
