Description

i have a problem to recieve some missing iotas from my old wallet. I did one transaction last year to the wallet 2.5.5. This year i bought another iotas, and transfered it to the wallet 2.5.5. Than the update appeard, i donwloaded the new wallet and now i am using the wallet 2.5.7. i creatded 100 adresses and only the second iotas i bought are showen up in the wallet.
I also have a new notebook.
The wallet 2.5.5 was on the old notebook, the new wallet is on the new notebook. I looked it up at the Tangle explorer and all the iotas are still there.

The strange thing is that all adresses shown up in the wallet show zero ballance, but in the wallet as i said the iotas i bouhgt from the second transaktion are showen .
