Have you tried to contact Darryl? email@example.com
He definitely replies as quickly as he is able (he must be swamped by now with all the referrals he's gotten)
Or have you tried a hard reset (on/off button and + volume hold for 10 seconds)?
Last resort, return this unit to the store where you got it and get a new one? I feel really bad for you! Nothing worse than having a reader and not being able to read!
