Query: DO NOT BUY - 2 HAVE CRASHED

I bought one - tried to add expansion card - it crashed. Returned it figuring it was a fluke. NOPE! Second one crashed too. I am using latest firmware (1.33) and have tried all of their suggested "fixes". What's worse - Rio appears to know they have a problem and continue to sell it without a solution.
