I was trying to recover my corrupted bitcoin wallet with your recovery tool, I used a Ubuntu 13.04 install CD, I managed to extract 101 key pairs, and I can find the recovered-wallet.dat file, however I couldn't move the file to anywhere, it says "Error opening file: Permission denied", I've got root by type in "su" command in teminal but still no help. I'm not familiar with Linux system so could you please help me with this issue? Thanks
