Help!!

This morning i've recived my brand new Riocar 10gb. I'm now at home, trying to upgrade it to v2.00b11. After checking, erasing, programming, flashing... the upgrade program seems to hang just when the player starts up showing the new Rio logo. The program says "Finding Pump" and the player starts. Then, the program says "Selecting pump device", and the blue line doesn't increase. After two minutes the program shows an error message. The payer still shows the Rio logo. If i unplug the player from mains and plug it again, it seems to start but then it says "No hard disk found. Contact ..."
Am I doing something wrong??
I've been listening to music for half an hour with no problem, before update it. I've tried with car2-consumer-v2.00-beta11.upgrade, car2-developer-v2.00-beta11.upgrade even with car2-consumer-v1.02.upgrade. In this case, the player doesn't show the "No hard disk found" message. I've updated the software to 2.0 as the instructions says.
Is my HDD broken? Will i have to send it back for repair? Please don't say yes.. I've not use it more than a half an hour!

Thanks in advance and sorry about my poor english, i'm trying to improve it.
