vpnc is sometimes a bit buggy. first, always check whether an instance of vpnc-connect or vpnc is running by doing:

ps aux | grep vpnc

if there is, kill it with kill and the process id you get on the second column.

i personally always use vpnc-connect instead of a direct call to vpnc (anyway afaik on most system, it's a symlink to vpnc).

could you post your config file? Located under /etc/vpnc/default.conf and /etc/vpnc.conf (remember that you cannot read them as normal user)
