thanks works, i lost 300k PND (and i backup my wallet 100% before i delete all files)
all in all it´s ok the wallet work
Probably you never had the 300k, you can go through you transactions and check them 1 by 1 to see where the difference occurs.
The total balance is always the correct one, you can also check it under "coin control" that's always correct.
There are 2 scenarios where this can happen:
1) You did some transfers between your own accounts in very rare cases this can cause your transaction grid to register something wrong.
2) With older wallets that were created before the first pandabank it can potentially happen because of the accounting system that was used before. But again there were no coins lost obviously.
I have wrote here i bought 483k pandacoins, i get the pandacoins today and the total balance show me the pandacoins and after the patch i don´t have the total 483k :/
You do, it must have been one of the older transactions. If it's confirmed and visible on the blockchain, you got it. No coins get lost, it doesn't work like that
otherwise satoshi would've created a really crappy protocol 
Ok, sorry for my bad english is okay...
