After a mishap that caused the version 1.60 patches to be pulled (story), they are now once again available in the same locations, with a bumped version number, so here's the appropriately resurrected news item: A full assortment of Neverwinter Nights patches are now available, the version 1.61 patch for the original game is on this Atari Support Page, and there is also an accompanying version 1.61 Hordes of the Underdark patch, as well as a new Shadows of the Undrentide 1.61 Critical Rebuild Patch. Thanks Frans.
