Thanx for the info!I will try and see.

Edit: successfully tranfered my hodls from v.3 wallet to v.4 with wallet.dat.Only the conflicted transactions are still conflicted ,the major volume of my hodls.These are lost as far as i can understand.I searched a lot but did not find any solution.Does anyone knows exactly what is the interest on V.4 wallet?I mean for no closed long term deposits.Is it right what is menrioned above?

Does anyone knows when optiminer.pl will support the new V.4 wallet?The people that are still minning at optiminer pool,how do they get paid if only V.3 wallet is supported?I tried to install V.3 wallet on another pc but it does not download the blockchain or has any active connections!
Any help would be appreciate.
