block error

[mintminty59]

I am having this issue when finding a block on my yaamp install can anyone help?

ThreadRPCServer method=submitblock
ERROR: CheckBlock() : first tx is not coinbase
ERROR: ProcessBlock() : CheckBlock FAILED

I have exactly the same problem. I tried to change the following coin settings:
RPC Type: POW, POS
RPC via curl: On, Off
Has submitblock: On, Off
Txmessage: On, Off

The effect was nothing

I think Blocknotify in coin daemon is working pproperly -- there are no any errors in coin daemon debug.log.

Is there any ideas how to solve it? I found many messages in forum describing the samr problem, but all of them has no answers.
