The thing is I'm not reinstalling, just running the application. I've also redownloaded it and it accepts my key on the download page (also rejects a made up key, just to test).
It is installed on my laptop too, and it runs on that, so it's only the original machine that has stopped working. I'm pretty furious actually. Pretty much nothing winds me up more than half witted license issues.
