at what point did you get that message? i don't recall ever seeing that error message. can you take a screenshot of that error? i'm not sure if the root file it can't find has something to do with .NET or something to do with not finding the PT save files or something to do with something else. when did you get the error? trying to run the program? did the program download OK from box.net? if it did not download well from the link above, you can download it from the bottom of this thread in the guide section:
Updated Virtual Seed Tray By Borgin that thread you will also find instructions for using the program as well as screenshots of the program.
btw, for some reason, for the last few weeks the last screenshot in that thread is listed as text:

instead of showing the picture:

if you need help taking a screenshot and posting it here we can teach you, it is pretty easy. in fact i think there is a thread somewhere around here that goes over how to do it in great detail.
