Maybe the reason was that only the source code is on Github and you've to compile it ;-) 

Hi Dan, and great work by the way, things working very well now.

Yes, and I must be one of those people who don't read everything. But I did google what I thought was a fair bit to find the right DL directory. Sourceforge, the Github came up in online tutorials, and clearly Github seemed most current. I didn't realise that it didn't contain a typical .exe. The forums all explained about unpacking the zip, and installing, but they didn't explain compiling. Anyway, hopefully this helps others.....
