I was able to reproduce the issue and will release a fix today.

hmm in fact ive issues to list the transactions.. and get the balance on the pool...

i pause it until i understand the issue (yiimp)

Wallet problem fixed

What happened?

While the algorithm switch was done most pools and users did not update there wallet. This caused a majority of the network to accept Scrypt blocks after the hard fork. Those blocks where accepted to the blockchain because more than 50% of the network confirmed them.

If you had problems, download the new wallet:

• Mac: http://www.amsterdamcoin.com/download/mac/amsterdamcoin-qt.zip
• Linux: http://www.amsterdamcoin.com/download/linux/amsterdamcoin-qt.zip

Seed node

Clients do not need the addnode configuration option, the wallet should have at least one connection to our seed node. If you want more connection (to speed up the sync) then you can add these nodes to your configuration:

addnode=37.59.27.14
addnode=85.24.169.215
addnode=46.119.246.239
addnode=76.180.145.102
addnode=83.87.162.162
addnode=84.200.17.20
addnode=198.245.50.213
addnode=85.214.152.3
addnode=81.169.137.12

To speed up the first syncronisation we have a bootstrap available here: http://www.amsterdamcoin.com/download/bootstrap.zip

If i send a transaction now whit the old wallet before the switch, are those coins lost? seems one disposed i made from a hot wallet not coming true.

Please add the following nodes to your config:

addnode=37.59.27.14
addnode=85.24.169.215
addnode=46.119.246.239
addnode=76.180.145.102
addnode=83.87.162.162
addnode=84.200.17.20
addnode=198.245.50.213
addnode=85.214.152.3
addnode=81.169.137.12

What is the TX hash?

Please perform this steps:
1) Backup your wallet
2) Download the new client
3) Start the client with the -rescan parameter
4) Check if the coins are still in the wallet and if the transaction is marked as orphan

If all goes well you should be able to send your coins through the new chain.

It only applies when you used the old wallet after the hard fork to make transactions. I will add it to the OP

coin is still cheap maybe this is the best time to buy more 

How many shops in Amsterdam even take Bitcoin? I don't get projects like this at all. Well, I get the intention is to make the devs hellsa rich but I don't get why they think they'll be successful. What's the incentive for business owners to accept this coin?
