L2TP on Cisco ASA 5505, just doesn't work??!

This is pretty urgent, client expects me to have this up by lunch today (!)
So, there is this Cisco ASA 5505 ver 8.4.
Most things work but now I want to setup a vpn connection...
I have done this 2 ways, first by using the "VPN Wizard" in ASDM and then 5 hours later removing everything and configuring from cli.
And it just doesn't work, client (WinXP & Win7) gets "error 792" and sometimes "error 789" (both indicating problem with phase 1, I'm pretty sure of that)
Googling on those gives a few suggestions none works.
All I get in the log on Cisco is the "Error processing payload: Payload ID: 1"
Googling on that only comes up with a few pages telling me this message is caused by an error. (Yeah, I could never have guessed...)

For the cli config, I followed this tutorial carefully (3 times actually...)
http://www.cisco.com/en/US/docs/secu...html#wp1117464

I'm using PSK for IPSec, entered same on Cisco and client - checked several times, this is not a password/PSK issue.
Ports opened on Cisco: 500, 1701, 4500
(For a try I opened all ports, no change.)

And here's the "show run":

Not sure if you meant to post that in here or not, but this really doesn't apply to Linux security.

Hi Pingu,

We’re sorry to hear about the VPN trouble you’re experiencing. Issues around VPN are a bit difficult especially since you’re crunched for time. Did you try opening a case with Cisco Support ( http://www.cisco.com/cisco/web/support/index.html) or looking through the Cisco Support Forums (https://supportforums.cisco.com/index.jspa)? One of both of these resources should be helpful in resolving your VPN issues.

Thanks,

Cisco Small Business Team
