there was no problem to do that; I said I would wait until I could reach Tamron on Mon, because I would also like to know what is causing the problem. Having said that, Cardinal Camera ALREADY REFUNDED me the cost of the item without requiring, or even asking, I to send it back. WOW
It may be the order of software installation. You may have to install the software first before pluggin the unit. Or your unit had problem during firmware update and generally it's very difficult to recover from failed firmware update. That is why I think you might need another unit.
