in my paper backup I have the 12 words for recovering root key and chain code. The problem is I don't know if this backup is from the online or the offline (is it possible?)(is that a problem??). The folder i found with .wallet and .watchonly.wallet and a paper backup is on my personal computer, so is accessible. The offline wallet is in Ubuntu, but since I don't remember the user password i can't access to the wallet. Besides, it's home directory is encrypted...

Hope this helps. Feel free to ask me again if I'm not clear with my explanations.
