Yes, as soon as I will be able to create a new account because LightWallet refuse it (failed to create account : unknown error) and https://bitshares.openledger.info/ Bad Gateway 502.

Same behavior with LightWallet (Windows) : no MEMO transfert seems ok, but with MEMO (I tried FOO) is doesn't work, no message, nothing (but in browser javascript console you can see error message).

When I try to create a new account (to test transfert to it) :

Failed to broadcast the transaction

I tried everything you asked, lock, send, unlock before send...

Hi, thanks to reply.

This is the first time I try to transfert BTS outside my wallet. I've always bought from marketplaces (poloniex, bittrex) to my wallet 0.9.3 then 2.0 and receiving is ok. My account have funds (several thousands). I just wanted to try transfert a little amount for test.

Unexpected discount at Poloniex

I've bought a lot more at 1700, thanks to margin traders.

Backup wallet.
Backing up the brainkey only recovers new accounts made from within the wallet, not imported ones.

Thanks. I used to backup textual data and I must admit I'm not very fond of binary data. Is there a way to get private keys (I can use cli wallet if necessary) ?
