New here, having a problem with my daughter's Vtab. Plug USB cable up to my PC, the screen doesn't pop up asking to mount as USB storage device, and the PC doesn't see it as a drive. I have another Vtab here (the one I'm supposed to send back to Vizio because the audio is not working), and it pops up and mounts as a drive just fine - so I know the PC and the cable works fine. Vizio tech support said to google online for updated USB drivers, but I'm not having much luck there. I did find a .zip on their site to download, but it's not a self installing file so I don't know what I'm supposed to do with the .zip. Can anyone offer me some direction for this? I hate to have to send back TWO of these things... my 10 year old would like to play with her CHristmas present before *next* Christmas. Thanks!
