    Hello all

    I am trying to connect to authorize.net and I am greeted with the following
    error.
    Unable to find an entry point named EnumerateSecurityPackagesW in DLL
    security.dll.

    I have included the stack trace which has more info. What little I can find
    on this deals with
    Web Services (which connection to authorize.net would be) but I am unable to
    find out what I need
    to do. Thing is, I have done this in the past with zero problems. Any help
    would be awesome.....Rob
