Well looks like I loaded the firmware onto the 568.2mm. I turn it on and it says Meridian 568. Hit display and it shows 2.5b9M/v262

What now?

Went to the Meridian software site downloaded Legacy and wired all the speakers as it said; however, as I moved down the menu I got stuck.
"The product connected to your computer is unrecognised . Please insure G68D is connected.... this version of the config program cannot be used with 800 series version 3 or 500 series products. Calibration failed.

Sure seems like I'm not in the legacy program or am I missing something, esp. as one option on the top bar is "room correction" and I know the 568 does not support it.

Any ideas?

G61R, HD621, 3xDSP33 (front, center left), 2xD1500 subs, 2xDSP420 (rears), Sonos everywhere.
