[rv120w][IKE] ERROR: packet shorter than isakmp header size

Greetings!

First off, I am NOT very network savy so please bear with me..

My wife wanted to be able to VPN to her office from other computers.  I purchased the RV120W as it appeared that the QuickVPN would be sufficient for my wifes purposes.  I installed the RV120W at her office with no real problems.

I have managed to install the QuickVPN software on my Vista PC at home. Using this software...

I can make a connection, through my home router (a Linksys WRT54G), to the network at the office.

I can Ping one of the computers at the office using that computers known LAN IP Address.

I can enter the setup menus of the RV120W using it's LAN IP address (I can only enter these menus from the WAN IP address when not connected via the QuickVPN Software).

I can see my connection in the RV120W's VPN User Connection Status Table under the Status tab.

However,

I cannot see this connection on the RV120W's Dashboard under the VPN tab. 

I cannot see any of the office computers, to include the one that I can ping, under Vista's "Network" page, I only see local LAN computers.

I cannot Ping any of the other computers at the office except for the one mentioned above.


I have provided both the Log file from the RV120W and the Log file from the QuickVPN Software..

Any suggestions, links, or comments would be greatly appreciated... 

Thanks,

Jeff

I checked the Log File from  the RV120W and it shows a repetitive error:
