When I first got my Windows 8.1 PC in Feb 2013 and installed Mio Desktop v7.5 0110, all went well and I was able to download new maps etc. Since having to restore my Windows 8.1 PC after getting a blue screen when trying to install webcam software, the Mio software does not recognize or see the Sat Nav when I connect it to the PC. Fortunately it still works on my Vista Laptop but the map update process is a lot slower on this, so I would prefer to get things working on my PC again. Any ideas?
