Reinstalling CWP Pro after Server Reinstall

My Centos Server crashed yesterday and I finally got it running again today after having to reinstall everything from scratch.

The IP addresses are the same as before, but CWP has not automatically updated to the Pro version (which I paid for previously). Is it simply a case of waiting for it to self update or do I need to take some action (eg run a bash script / contact support etc) ?

Any advice gratefully received.

Thanks

UPDATE: After checking my account, it seems I actually paid for CWP Pro to be installed on a different IP Address to the one I'm currently using.

As the year had nearly expired, I cancelled that subscription and took out a new one with the correct ip address. Running the bash script 'update_cwp' installed CWP Pro immediately.
