I have seen this issue before, and yes, it is safe to install the new firmware over that particular version. I do apologize for the confusion, as I can appreciate how this would be alarming, but we are aware of it and your new firmware should load without issue.
I have downloaded the upgrade V2003.2. When I input the USB stick into the slot it says that my current version is 999999 do I wish to continue. Just for your information I live in Canada.
Has anybody seen such a weird message or version number. I would like to know if it is safe to continue with the firware upgrade.
