Hi Everybody!
I try to use new wallet but with no success. I get this error:
invalid -rpcallowip subnet specificatoin: 127.0.0.0What shoud I do? I have the old wallet 0.8.6.4 but it can not synchronise (it gets to some points of synchronising but then stops).
Anyone would help?

And maybe there's some download available to synchronise blocks immediately?
My advice is to download and install the last version of the wallet. Get rid of everything except wallet.dat.
Last version of the wallet is in OP of this thread.
You can find a snapshot of tbe blockchain here:

With the wallet closed, unzip the file and transfer its contents onto pesetacoin folder. After that, open the wallet and you should be sync as of more or less a month ago. Wait till the wallet syncs completely and you will be done.
Be sure to protect ur wallet.dat file if it has coins and personal addresses you don't want to loose.
be careful with your wallet.dat. That's very important
