If you download the "merchant utility" here in the free section it will switch the p5 info to p4 info for you :-) I use it to make my free items more compatible with p4 and pro users as I only have Poser 5. It works very well, I don't get any complaints that 4 users are haveing problems with the files. :-) If you open the cr2 files (or pp2 files as is the case with most of my posts) after uing the utility the information is organized better for editing too.
