tunctuncer

Hi there. I just bought my JTV 69 and started updating the flash driver. After it stayed like 5 mins and downloaded very slowly, the massage appeared saying that the connection is lost. Since then the dap just doesn't work. When I press on the Varian button it just activates the pies pickup but nothing happens when I switch between different guitar models or different tunings. How can I update or re-install the driver on the JTV?It's now just a regular guitar. Please help! :((
