Hello Anthony,

What version of libcurl.NET are you using? If it's a
version prior to 1.3, perhaps the problem is some kind
of security issue relating to the fact that the
earlier versions are signed assemblies. If not,
perhaps we can take the issue off-line, hopefully
resolve it, and then post an answer to this board.

Take care,
Jeff
