I've had the same issues getting through to teambg, but
here's a link to an Infinity Engine Editor, and I think the VB6 package is at the top of the page. Now all you need is either near infinity or shadowkeeper to give your characters your custom weapons. I was big into custom weapons a while back, but gave it up. I had also started work on a kit, but it was a lot of work and I didn't have the time anymore. But it's a lot of fun, so good luck.
