I recently took my computer to a shop to be repaired because of virus related issues . I didn't have a complete reinstall , but some programs were removed and now my MP3 player will not show in my computer or charge . I went into device manager and see a ! exclamation point next to USB mass storage device ,so I uninstall and click action and scan for hardware changes , and see a pop- up at the bottom of the right side of my PC letting me know there's new hardware found , only nothing in my computer , so I tried updating the driver and firmware for Sanza clip and while it's trying to update , states no updateable Sanza product has been recognized . Any advice , because I think something went wrong when the PC was repaired .
