I can't really help much but I have to ask if you are using a
pre-compiled .dlm or did you compile it yourself? Just wondering since
I know this .dlm has been around for a while and I would expect issues
if you were using a precompiled .dll that is packaged with the library.

See. Not very helpful, but we have to start with the obvious first :)
