Hmmmm couple of people have reported a strange path issue with NNWInstaPost. So here is version 1.01 that seems to be helping that odd issue. Do let me know if that's still not working
Update: So that seems to have fixed things for people with the issue. It appeared to be some odd caching issue that I can't consistently repeat - you know, the kind of bug that is very irritating ;)
Thanks to: Michael L, Arthur M, Woody G, Andrew J, Matthew D, Joshua B, Rich M and others for their help tracking this one down.
