Maple Crashes

You could try putting a copy of the dll in the maplestory directory. My computer has many copies of several versions of this dll since it seems most applications that use it install a copy in the applications directory.
Other than that, no idea. There are all sorts of different problems happening, as if nexon can't make the program entirely compatible with any computer.

Edit: that file dates back at least to 2003. Lol. No wonder that there are problems with Vista and 7.
