I upgraded one of my sites from Aloha 6.2.16 to 6.4.29. Server is Windows 7 Pro 32-bit. Everything seemed to go fine on the back of house but the terminals would not come up. They kept saying "Exiting- data file error" and rebooting. Tried deleting the Aloha folder on the terminals and re-installed terminals. I reverted back to 6.2.16 for now. Any insight?
