I just updated a Lombard (333) that still had 8.6 running. 9.2.2 went on fine with full function but after I installed 10.2.4, the keyboard stopped working (Tab and Caps Lock still work but that is it). No numbers, letters or function keys. I have loaded 10.2.4+ (.2.8 and even 10.3) on over a dozen Lombards and never had this issue before, Can anyone help. I got this for my son and I really need it running ASAP.
