ASA 5505: Regular translation creation failed

I have recently installed an ASA 5505 and created a 'box to box VPN tunnel for purposes of electronic prescription. I have a VPN client app that I use to access a radiology image database at my hospital. When I click the VPN Client app (Cisco VPN Client version 4.8.01.0300), the client app states that the tunnel is created. I then try to access the radiology website using IE7 and no response. When I view the ASA 5505 syslog, I get the following error message:
Syslog: 305006
Source IP: 216.xxx.xxx.xxx
Description: regular translation creation failed for protocol 50 src inside: 10.qqq.qqq.qqq dst outside: 216.xxx.xxx.xxx.

My current config is as follows:

Any ideas to allow the CISCO VPN Client app to function correctly?

Thanks in advance

Your config tries to setup site to site VPN but you are describing remote access vpn and you don't have any configuration for remote access VPN. Your ACL is not complete. YOu need to allow the inside subnetworks through the VPN tunnel through to the subnetwork that the servers are on and vice versa.

Correct, I have a site to site VPN created that I need to maintain. How do I create the specific ACLs to permit the vpn client software in my network to communicate w/ the server? I did the Site to site w/ the GUI interface.
Thanks

Assume this:

Inside network(192.168.0.0/24)----asa
asa----(192.168.1.0/24)

If you have a layout like above, you need at least 2 ACL entries, one to bring up the tunnel between the ASAs (tunnel peers) and one to allow interesting traffic between the two subnetworks behind the ASAs.

Okay,
I thought I had made the right changes to my Access list statements, but still no go. Below is the current config (minus all the crap-ola. My inside network is a.b.c.0 and I'm trying to get to the x.y.z.0 network using a CISCO VPN Client (inside my network). I have a site to site vpn tunnel to EE.FF.GG.HH network that is working fine.

I have never setup a vpn for remote users on a ASA but don't you need to also define a VPN pool in the config?
