Purchased boards last year in a group buy with some friends. Finally managed to install. One in Getaway (all good), one in White water (first one is the board giving errors constantly). I installed another in White water and it is working (aside from the whirlpool audio, which seems corrupted in the sound file, there are other mentions of this in the forum. I attempted install of error board in GNR, and same result. Installed my remaining board in GNR and it appears to be working. Is there anything I can try with the error msg board, or is it possible to ship it back for repair or replacement?
