Hi,

I get this error when trying to sent btc from electrum (v 1.9.8 )

Code:

The transaction was rejected by network rules : error 16: mandatory-script-verify-flag-failed (non canonical DER signature)

And I get the same error if I try to sweep the key to a new wallet
The key is from a block I mined in 2011, could it be related ?

Thanks
M.
