Last night/this morning I installed Silkcoin wallet 1.1.0.16 on a different computer, which has never had a wallet on it before.
We need more details because Silkcoin developers use differents OS like Windows 7 32/64bits, Windows 8, Ubuntu, MacOS, ... and nobody has that problem...
I had the exact same issue. The wallet crashes when I send SILK. It's not due to a problem with the computer then.
Where coins of this new wallet come from ? Backup of your previous wallet.dat ? importprivkey ?
