problems with TLSv1 curl on Windows

We have a connection setup to a vendor that will be using only TLSv1 from now on. Before we would connect to them using the SSLv3 option. Now, when I want to connect to them I get an error:
* successfully set certificate verify locations:
* CAfile: ca-bundle.pem
  CApath: none
* TLSv1.0, TLS handshake, Client hello (1):
* TLSv1.0, TLS handshake, Server hello (2):
* TLSv1.0, TLS alert, Server hello (2):
* error:140920E3:SSL routines:SSL3_GET_SERVER_HELLO:parse tlsext
* Closing connection 0
curl: (35) error:140920E3:SSL routines:SSL3_GET_SERVER_HELLO:parse tlsext

We are using curl 7.40 and running W2K8 R2.

We've tried multiple ways to connect with multiple options, but all this to no avail.

These are the commands that we tried:
curl.exe" -v --ssl-reqd --cert <certfile>.crt:<pass> --key <private_keyfile>.key --cacert ca-bundle.pem --user <users>:<pass> ftp://<ftp_server_url>/
curl.exe" -v -TLSv1 --ssl-reqd --cert <certfile>.crt:<pass> --key <private_keyfile>.key --cacert ca-bundle.pem --user <users>:<pass> ftp://<ftp_server_url>/

The old command we used and which worked just fine is:
curl.exe" -v -SSLv3 --ssl-reqd --cert <certfile>.crt:<pass> --key <private_keyfile>.key --cacert ca-bundle.pem --user <users>:<pass> ftp://<ftp_server_url>/

Any help would be more then welcome!
