windows 7 sftp doesn't connect, ssh works

I use BitKinex on Windows 7 as SFTP client and PuTTY for ssh remote shell.

Out of the blue, sftp stopped working, but putty still connects normaly.

Tried disableing firewall (Avast Internet Security), no changes.

I was under the impression that sftp works "over" ssh, so I am confused right now...

Where should I look for the problem?

ps. using private-public key auth for ssh and sftp.

edit: BitKinex log:

You're right about SFTP being an SSH protocol. Did you recently install updates? I know SP1 recently came out... maybe it has something to do with that... – beatgammit – 2011-04-05T07:23:24.857

Does BitKinex have any sort of debug output? Does it give any messages as an error? "stopped working" is a pretty all-catching problem and it would be really useful to get more information how its breaking. I've been trying to find out where to get this information from their website but I can't see anything obvious. Personally I use winscp. – Pricey – 2011-04-05T07:58:50.330

Have you tried WinSCP, or the psftp client that comes with PuTTY? Do they work? – user1686 – 2011-04-05T08:58:11.380
