PCTCPAPI is the first lower level interface that the ftp Software
WinSock.dll calls. I'm thinking that you only have our WinSock.dll
but not the rest of the protocol stack either in your path or on
your system. Look for ethdrv.exe or vxdpctcp.386 and if you don't
have either of those, you don't have the meat of the protocol stack.

Just to clear up potential confusion, different Windows Sockets DLLs
from different vendors look the same from the application side, but from
the bottom up, they look entirely different and aren't interchangeable.

If you have any problems, let me know and I'll do what I can.
