Ur node sends a transaction to all peers. Before sending a transaction u can do a little test, just send 1 NXT back to urself. BCNext is working on resolving this issue. Most of nodes have 256 Mb reserved for JVM which is not enough.

Blacklist is for nodes that announced incorrect address or were unreachable. Remove nodes with sane address from the blacklist time to time.

I have problem with one of my sell transaction. Buyer admits receiving coins and then after some time next were gone from his account.
Was those coins stolen?

Here is transaction
 http://88.198.210.245:7876/?request=getTransaction&transaction=18063112106693460272
Can it be treated as proof that i sent coins to buyer from account 818877006463198736 and he received it to address 3791936988034107349?

Perhaps. In Russian subforum I saw a message that someone already picked a short secret phrase with 1 NXT on the balance.

I'll assume Bossland is honest then and used just weak secret phrase.
Let it be warning for all NEXT users, Use extremly strong phrases

Win7 x64, JRE 7.

Deleted all *.nxt files, run the client. Launched with java -Xms512m -Xmx1024m -cp Nxt.zip Nxt

It did catch up to the latest block. But few minutes later it's at 0 blocks again and this error is given:

[2013-11-29 22:41:28.814] Saving blocks...

java -Xms512m -Xmx1024m -cp Nxt.zip Nxt


Tried that then it reset back to 0

then tried the normal java -cp Nxt.zip Nxt but it cancelled saying block was broken. Had the NXT block\accounts etc zip u posted though and built from there using the normal java start up command.
 

Woah, seems like we have some issues going on here now. My client is showing a balance of 0.00 in the top right header, transaction count jumped around on loading localhost. Blocks section is showing -4399 blocks and 4459 orphaned blocks

What is the difference between the windows Client and the online wallet http://88.198.210.245:7875/? Did I just need a Password to access the wallet? what is of different people use the same password (secret phrase)?

Thank you, that fixed it.
