Ok, finally got it fixed. They sent me to Office Depot to buy a thumb drive with no frills. No security software, no encryption, nothing, just a storage medium. I used it and it worked. I had bought a drive a couple days ago that did have security software on it,because Best Buy didn't have anything else, but I did a total format on the drive. It wouldn't work. So apparently that's the secret. A no frills thumb drive. Someone had mentioned that in a different thread, but I didn't realize it really, really had to be no frills. Anyway, sorry for your problems, hope you get yours orked out. I know it's a pain to ship back.
