Haha, yeah, I generally drag and drop too. It seems like publishing the project incorporates the dlls into the resulting acknex.dll, cause when I try to copy the dlls into the executable folder, the executable crashes immediately, but when I leave em out, the program runs without a hitch...minus one of my dll's ability (the same one appears missing regardless of which dlls exist in the exe folder). The dll that isn't activating is the same one I've used unchanged for months, so I'm very confident that it is working properly. I've got 5 dlls altogether, and I've tried every combination of them in the exe folder with no luck.
