I've had to install, unistall, delete 3.07 about 12 times, before finally getting it to load, install and run OK, but that's only since attempting a re-start of lap-top (Acer) factory defaults (anyone know how to do this as Acer Empowering Technology won't any more, I had used it before), which wouldn't work, so attempted a re-install of Vista. 3.07 installed and running well, I'll have to post a polar diagram as reception is better than with 2.01. I've had to spend about 10 hours re-loading Vista, then all the updates, SP 1, 2 etc., but I'm 99% sure this is a Windows problem rather than 3.07 as such.
