Lucas P3D editor refuses to load

Hello

So im looking to edit files of simpsons hit and run and tweak around with the p3d editor

but when i run it, it displays a grey with unclickable buttons and an empty list, and thats it

i have tried using it in compatability mode and running in administrator, all of that, but to no avail

i use windows vista (yeah i know) and i can't find any information that can help my problem

i also downloaded the RSD editor as i was looking to add in some sounds, and it justs displays unclickable buttons

Pretty simple fix. The P3D Editor lacks an "open" button. What you need to do is find the P3D you want to edit, then drag it into Lucas' P3D Editor. You can then edit it however you please!

Thank you so much, it works now.
