I'm opening a file trough FTP with:

pnFTPFile = FtpOpenFile(pnConnectHandle,@lcSourceFileName,GENERIC_READ,FTP_TRANSFER_TYPE_BINARY,dwContext)
..
..
THEN I CLOSE IT WITH:

=InternetCloseHandle(pnFTPFile)

WHEN I TRY TO OPEN THE SAME FILE IN THE SAME CONNECTION THE FILE CAN'T BE OPENED.

How can I release that buffer or whatever it is?
Do I need to:

=InternetCloseHandle(pnConnectHandle)

and then reopened again?
