I'm sorry, can you be more concrete in your messages?
do you have something in this output?
# cat /proc/net/ip_conntrack 

Most likely, you need to add the line
/sbin/modprobe ip_conntrack "ip_conntrack_enable_ve0=1"
somewhere in your init scripts and reboot the machine.
Or remove this module and then reload with the option provided.
I guess that you simply did modprobe when module is already loaded, in this case modprobe reports the success but does nothing.
