I did check the address and it says it's there. It says

transactions 2, total received 0.30500001 BTC
Final balance 0.30500001 BTC

Hello,

I am looking for help with restoring the balance in my Bitcoin Account.

In December 2013, I received 0.305 BTC into my bitcoin core wallet. I did this on a PC running windows XP.

I then forgot all about it and haven't used the PC until now. When I access this PC now, everything is fine, no problems at all, except. The Old PC can no longer connect to the bitcoin network.

I installed the latest version of the bitcoin software on a windows 10 pc and it then took 3 weeks to sync! When it finished it couldn't find my transaction, so my balance is 0.

I looked on the net and the advice I got was to backup the wallet on the old PC, shutdown bitcoin on the new PC and copy the wallet ID into the existing folder. So, I did this and when it retarted it took about 4 hours to go through the rescanning.

Now, it's finished there is conflicting information on the main screen. The balances read:-

available 0.00000001
pending   0.00000000
Total     0.00000001


On the other side of the screen, it talks about recent transactions. This screen reads

received 10/07/2017 12:42 0.00000001
sent     29/12/2013 02:22 0.00200000
received 21/12/2013 19:31 0.30500000

Everything is OK on the old PC, except the transaction in 2017 isn't there, but that doesn't matter of course!
