458920 Problem with IPtables based script

I have an Iptables based script, iplist (iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.( The script installs without problems for a dedicated server but for a VPS it fails. I installed the script succesfully but when I attempt to start the service ,IPTables returns error as shown below: /etc/init.d/ipblock start Starting IP blocker daemon: [ OK ] [root server~]# iptables: Unknown error 4294967295 ipblock[32513]: error: failed to start, cleaning up /etc/init.d/ipblock start I need someone to help me fix this. The VPS distro is Centos 5
