Hrmmm, OK thanks for your input. Is there a newer version around? & How does this code simply 'cease to operate'?

Well the problem has cleared up, apparently due to closing and opening labview as instructed, which I thought I did previously but I must have been mistaken. Have a nice day.

I'm trying to make an application with SSL. This library looks great. Unfortunately when I open this in Labview 2010 I get some VIs that aren't executable; SSL Start Session.vi is one such example. For any inputs to the call library function node which are 'Adapt to Type', Labview is rejecting that wiring with "Polymorphic terminal cannot accept this data type". In this case these are where "security context" and "socket refnum" are wired in.

Does anyone know what the problem might be here? Has something changed in call library nodes or in the refnum types somewhere between 7.1 and 2010 that would create an incompatibility? I have no versions available beween 7.0 and 2010.

The call library function is using lvNetCon.dll, which I assume is a wrapper around OpenSSL. Is there a .h file for lvNetCon.dll around that I can refer to?
