Why, everytime I change my screensaver to NONE, do I have to re-register my Particle Fire download key and, re-install Particle Fire before it will run again on my pc? I have a 2004 Sony Vaio 4.3 gig computer so, this cannot be the problem. This makes the second time this has happened since, I re-downloaded to my new pc. I first purchased it 06-12-05 and, it isn't supposed to expire until 11-07. Can you please explain this to me or, make some kind of change in the programming, so that when I click NONE, on my screensaver, I can put Particle Fire back on without having to re-register, and re-download, before I can run it? We think it's really cool and, it's the only screensaver I like and, will use.
