thank you for your help
but I have problems with BTC Wallet
he asks for a password, but I did not put it.
how much I remember the password did not set
The fact is that I registered it in ~05/06-2014 (old version wallet) and never used it, the file wallet.dat saved
it weighs only 64kb
on the new version (I try to sign messages) it weighs ~1.5 mb
I thought maybe the problem is this
I can not sign a message
(
there must be another alternative to unlocking the account )
