Put the Micro SD into a card reader, and check first that the TTMENU.SYS file exists. If not, add it to the card. If it does, it may be corrupt and require the file to be recopied onto the Micro SD. I would unzip Firmware 1.07 again and re save the eng folder contents to the root. If this file is corrupt, the others may also not be 100%. Unzipping doesn't always work every time.
