If you guys get that fixed I would suggest selling it on Ebay and buying a decent entry level gun with the money. I had a VL genesis and it chopped all the time. I only used it once and I couldn't get it apart to clean it so I decided to smash it open with a hammer.
Go to the Dropzone site, they have drawings that will help you out. It can't be too much, they are very simple guns. Broken seal? Piece of paintball jammed in it? Something like that. Which two pieces that you can't get apart are you talking about?
