[SOLVED]: ProFTPD will not reinstall - Requires Webmin 1.870

Getting this error whenever I try to reinstall ProFTPD.
Failed to install standard module : Module proftpd requires Webmin version 1.870 or above
I have checked and I am running Webmin 1.860 but there is no update (in the updates section) to update to 1.87 so how am I supposed to reinstall this? I had removed it as I wasn't using it but now I am I need to reinstall.
NOTE: It appears there is a 1.870 version but only on the Pro side. Can someone give me an update of when this is likely to be release on GPL?
