Hi, Spit... 1:On first running, PBooost will first find the path to your most recently installed copy of Poser...(takes about 1 milli-second!) then it asks you if this is the Poser you wish to work with. You can point it to a different copy of Poser at this stage. This takes no extra time at all! During use, if you need to change PBooost to another Poser installation, click "Change Poser Path" in the menu and find the Poser you wish to use PBooost with. 2:PBooost is half expecting people to have PNGs and RSRs together and this causes no problems!
