Dear zackesh,

The door problem is likely due to the lever above the counter wheel not being down all the way. My suggestion is to learn to do the entire process inside a changing bag. It really isn't very hard (if I can do it, trust me on this, anybody can). I pre-clean 20 cartridges and put them (disassembled) in a soup bowl. I add a second bowl for the finished product. Then, without ever opening the bag, I load the film in the loader and go through the process of loading 18 cartridges counting 38 clicks per roll. I use Scotch Magic tape from a small disposable dispenser.

With a little practice, you can load an entire roll while watching a sit-com. Make sure you've used the bathroom before you start. ;>)
