I can confirm that sha256sum of ppcoin-0.4.1rc1-win32-setup.exe is: c0fa41ad46ee6c27571a39e6bac4ef68d92f6e2b8c53919472ead98bc31c4bdb

Before attempting sending of transactions, you should first confirm you are on the right blockchain fork. You can do this in debug window console:
getcheckpoint
{
“synccheckpoint” : “000000000000000788eb52cb07e75fe19503b389f69342b6370a3ef43544e269”,
“height” : 204717,
“timestamp” : “2015-11-10 23:35:16 UTC”
}
getblockhash 204717
000000000000000788eb52cb07e75fe19503b389f69342b6370a3ef43544e269
If your checkpoint height is greater than 204717 you are on the right fork, and further confirm the blockhash of 204717 is above.
Test transaction sending with small amount first. For sending to exchange please first confirm with the exchange that it is accepting deposit, also test with small amount first.
That is correct.
Successful source build of 0.4.1 on 32-bit Linux. Up and running again on the correct blockchain. Kudos to the devs for the rapid response.

This was a helpful reality-check after updating Windows wallets to v0.4.1 RC1 and a small test between updated wallets has started confirming. Thanks for the info and a big thumbs-up to the outstanding community effort that expedited the fix.
I am a newbie and just started 3 days ago with Peerunity, version 0.1.1 on Windows 10, 64-bit version installed I am also having the same invalid checkpoint.
Can any give me directions how I can solve the problem ?
[member=292]whifmoi[/member] Yes, http://bkchain.org/ is working on the correct chain
I was testing the first ppc exchange: btc-e, it also is working ok

You must uninstall Peerunity 0.1.1 and then install Peercoin 0.4.1 RC1:

Thank god, I’m on the right fork. Withdrew a lot of coins from BTC-E lately.
Peerunity 0.1.3 and ppcoind 0.4.1 is working fine for me on Linux 64-bit.
https://peercoinexplorer.info is now on the correct chain and the London trusted server was on the correct chain already. Therefore the Android Peercoin wallet is working, but if anyone finds any issues please let me know.
Update: Linux build of 0.4.1 RC1 is now available, which should allow linux node running 32-bit binary to get back to the supported blockchain fork. Upgrade is only necessary if you were running 32-bit binary instead of the 64-bit binary of the 0.4.0 linux build.

Please always backup wallet before proceeding. Also note down your total balance/stake.
Stop/exit version 0.4.0.
Start version 0.4.1 RC1.
Be glad that BTC-E was on the right fork 
Peerunity for OS X has been added to the 0.1.3-RC1 release and is available for download from the official Github repository.
