I signed up with the WOW UK Met office some years ago and fed info which shows up on the NZ weather map. This chugged along until apparently sometime early this year. Unlike WU, where if you stop sending data, you get a nag message, the WOW system doesn't care and unless you monitor it, loss of communication slips under the radar.
It wasn't until I moved everything to a new computer that I realised that WD wasn't sending data and try as I might I couldn't get it to do it. I even reset everything in WOW.
On my old computer system, I tended not to upgrade the WD software, being of the mind that "If it aint broke, don't fix it". However early this year, because I had was having a few problems, I decided to upgrade and download the latest upgrade version (NOT THE FULL INSTALL). Everything appeared to work fine, but it appears that's what clobbered the WOW comms.
Yesterday, I logged into Weather-Watch and searched for WOW info and came across the info that the WOW interface had changed from FTP to Cron and that the file cronwow.exe was required. Looking in my wdisplay directory, this file was missing. Checking the zip file of the upgrade, I couldn't find it there, so I downloaded the full install, installed it on another computer and copied the file over. Voila! Up came my site on the Met office map.
I suppose this illustrates the danger of only doing occasional software upgrades which might mean that files included in one upgrade may not be included in later ones and a full install perhaps should be done instead of using the upgrade package in such a case. I was reluctant to do that in case I had to do the station set-up again. I'm not sure if that's the case? Anyway, I thought I'd relate this tale so that perhaps it might assist someone further down the track.
