I don't think you need to because the wallet info is stored elsewhere. I've reinstalled NEM Client several times and always I was welcomed with my wallets.

well ... I copy+pasted the 8 words from that

Here I have been meaning this discussion (and vote?) of this https://forum.nemcoin.com/index.php?topic=2531.0  +  https://forum.nemcoin.com/index.php?topic=2540.30 
Has it been ended... is there a conclusion or a common consensus? At least I heard rumours that one of the most clamorous NEMsters might have changed his mind from 4 to 8  
 

Well as I've said time and again.
You people need to give more information. "It doesn't work" won't get you a lot of help.
Tell us about your system.
Do you run standalone or webstart ?

My notebook is weak, HP 15-g000sr. Today blocks 25677-... had 60 tx/block in sequence. I get 'NIS is not available!' Two days before it works 24/7 fine, port 7890 is opened.

I run the client on Rasperry Pi devices whith Raspibian (debian wheezy 7) and works fine. Of course: For 60 transactions it'll have some work to do.

I noticed if you let it alone, usually works fine. It'll sync whith others nodes, as it lost time processing transactions.

This client 0.4.17 is really more solid then the previous one.

 

Try sending to an account that already has some out going transactions.

GOOD ad here, the topic is so hot.

When did this happen?  Is each stake now worth 2MM NEM, or has total supply been arbitrarily doubled?  Reasoning?

4,000,000,000 has been the plan all along.  Arbitrarily doubling makes no sense.  It could serve to derail confidence though.  Foolish.
