Reloading mp3 software (by 4 users)

another solution i tried is : erase all information from the device ,take the battery out....make sure the item is not connected to the network in the following 10 minutes, because its going to loose the reserve power,,, then connect the device without a battery on, reformat the device, put it on a default mode, and run the antivirus into the device....but if it doesnt work, the best solution will be the lawyer and the lawsuit.. cause its making people loose there money in big amounts,because its not expensive, and not only one person buys this stufff...imagine that the error 41 is in a million of devices, it will make nextar corp.. more wealthy.....
