It is past 375000 block and still doesn't work.  Getting the same error message.  Something about how the mined block failed verification.  and it is saying invalid time stamp.  Maybe a timing setting somewhere is not configured correctly.  

edit:  I think I see the problem now  "strict time sync while mining requred now"   It must be too strict because nobody can mine it now.

edit2:  I changed the time server from "windows.com" to "nist a" server.  It seems to be working better... at least not getting the errors immediately but haven't mined a block yet.  But it does look like it might do better under the new time server.

edit3:  NOPE  got the error again.  damn this sucks

If  Exchange is really small one why it's so expensive?
For this price you can list your coin in decent exchange.
Or find small one with much lower listing price...
Or I something not understand...
(Maybe I know nothing in that things...)

that's the right decision.
I respect.

yes, everything is back to perfect now.  I guess patience is not my strong point in life lol.  Good work averting the attack!

After switching to BUILD #39 I've found many blocks:
But balance in my wallet not changed...

Why???

Should I delete Roaming/sld dir and resync?

I mine in wallet app with start_mining command.

Deleted and resynced blockchain but it doesn't helped...

https should be implemented last week, but attack had all of our free time.
But it will be ready till March, for sure.
