No high-priority updates for your computer are available -- checked.
I just tested couple of routines I have, VFP modules with direct WinINet calls -- no problem at all.
API calls tested:
FtpFindFirstFile
FtpGetCurrentDirectory
FtpSetCurrentDirectory
InternetCloseHandle
InternetConnect
InternetFindNextFile
InternetOpen
FtpCommand
InternetGetLastResponseInfo
InternetReadFile
It could be some Windows firewall issues.
