I had to update my drivers to 4.2.5.1 and after doing so I'm not able to update my flash memory. I tried both ways, from the Line 6 Monkey and by downloading the .phf file and loading it that way and both fail every time. Now I can't use the POD HD500 Edit 

Here is the error:

File download failed.

Reason: (Code 80002914) Unsupported protocol.

Then says to take off pop-up blocker, which i did, still didn't work. Then I get this error:

POD HD500 update failed.

(Code 80007211) Firmware update timed out waiting for response from the device.

Try the update again making sure the cables are connected.

What can I do? I've tried everything I can do to my knowledge. Thanks to whoever helps me out!
