Server closed connection

I've used SFTP for years. Just upgraded to version 2. When I connect to my website, I get these messages:

[10:33:33] An established connection was aborted by the software in your host machine.
[10:33:33] Server closed connection

I get these messages whenever I try to expand a folder on my website. A red "X" appears on the folder. This is the first time I've used SFTP since installing WinXP SP2.

Shutting down Zone Alarm, NAV, Spybot S&D, and Microsoft AntiSpyware doesn't help. I'm not running the Microsoft firewall.

I'm running through a Linksys WRT54G router with wireless features turned off. This router is new to my config - it replaced a Linksys BEFSR41.

So, I've got new software (SFTP v 2), a new router, and a new Service Pack for Win XP.

Any suggestions for resolving this conundrum?

Post the complete log.

Hi, [[[TRYPASVPORT][/TRYPASVPORT]][/[TRYPASVPORT][/TRYPASVPORT]]][/[[TRYPASVPORT][/TRYPASVPORT]][/[TRYPASVPORT][/TRYPASVPORT]]]

Thanks for your reply. I set SFTP to PORT mode and tried again. Here's the log:
