F5 Remote Access Client - 'You do not have access to the Network Access Connections'

I'm trying to use the F5 BIG-IP Edge Remote Access Client for VPN access, but when I try to connect I get the Notification message:

 

You do not have access to the Network Access Connections.

 

Please contact your system administrator.

 

This appears as a 'Configuration Error' in the Notifications window.

 

I've tried installing the client on a Windows XP machine and a Windows 8 machine - both have exactly the same problem.

 

I've used the BIG-IP Edge Components Troubleshooting tool (f5wininfo.exe) and this shows a green tick for everything except FirePass Components/Terminal/utunres.dll - not found. I don't know if this has any relevance or, if it does, how to fix this.

 

The software was provided by the company I work for for remote access.

 

Any help/suggestions would be much appreciated!

 

Thanks,
