Upgrade okcash wallet to ver 5.0.0.3 on ROKOS

[50y7]

Hello everyone...
I have installed Rokos V10 to have an okcash node, but the okcash wallet version (5.0.0.2) does not update teh database. I update de blockchain manually and it work, but not add new blocks.
How can I upgrade okcash to version 5.0.0.3?

Thanks
