you can send me a PM, if you want me to try to recover the wallets, but i need the wallets and the passwords.
yes it sounds like a scam, but your bitcoins are lost anyway, unless you can fix it yourself.
If in a few days nothing else works I may very well take you up on your offer.
Did you by any chance change your keyboard layout/input language?
Try typing your passphrase into notepad, does it type out correctly?
Keyboard layout is the same. Typing the password into notepad comes out correctly.
Did you have a firewall running?
Did you have antivirus running?
Was hotel wifi insecure - no encryption or using WEP?
I had a firewall and antivirus (MSE) running, and the wifi was unsecured. Since posting I've done a full scan and nothing was found by MSE.
Memory is not always a reliable tool. Sometimes you are absolutely sure you remember something correctly, even when you don't. I have wasted a phone by entering the wrong PIN-code three times; at the time I was absolutely sure it was the right code, but a day later I realised what my code really was. I recommend meditating before going to sleep; clear your mind of what you currently think is the correct passphrase and ask your mind what the real passphrase is. Even if you don't "get an answer" during your meditation, since you have been focusing your mind on it, the next morning you may suddenly get it. Also stop re-entering the same passphrase that isn't working, you are only confirming an incorrect memory and making it stick.
Thank you, this is fantastic advice. I'll meditate and wait for a while before trying to enter my password.
