lerxst - the 562 should not have to go anywhere. you should be able to do a hard-reset of the 562. check the manual to do a hard "type" of the unit (hold down up arrow and hit the power switch?). when you retype it should reset everything.
or if i'm misunderstanding and you did something like sent a 2.8 568 upgrade to a 562 then you're on your own!
also, i highly suggest setting it all up together ('tho if your 562 is fritzed then i grok). i bought my 562 after my 568 and it was a pain to redo a lot of stuff.
