Just in case anyone else is tearing their hair out like I have been for the last day or so. I thought I'd report here, that WSPR and WSPRnet.org do not accept anything greater than a 6 character QRA locator. I had changed it on my setup to 8 characters to try to locate me nearer to my house on the google maps on the site. I hadn't noticed at the time that it had stopped accepting my spots, and started searching for the reason why.
Apologies to Joe, for bombarding him with emails whilst I tried to find the cause suspecting everything other than the program and my own stupidity.
