Problems with RBI cage

[twh]

A couple days ago I received my RBI cage, it took a while due to weather and such. I got the package with a few holes in the packaging, and opened it to find that it had two small dents in it. I didn't want to return it, so I didn't mind. However, after setting it up, I woke up to find that the acrylic door no longer works? Did it warp over night? I'm really at a loss here. The left side no longer fits and it's really frustrating that, that would just happen for no reason.
Does anyone have any ideas how to fix it? I'm not very handy, it just looks like the acrylic door is too big to fit into the hole it was made for... Btw it worked fine before.

why not contact Rich at RBI ??? i've never worked with him but he has a stellar repuation with customer service.
