Guys, I got my balance back in my wallet. Thank you very much for your support.
Very much appreciated, warm regards!

Thank you for your answer. Yes after w whole day immersion into bitcoin infos I start to get a picture how it works and how to read block explorers (gosh it’s simple once you get it but drives you crazy when you don’t).
I haven’t tried exporting the Keyes yet since I’m trying to resync core in the hope that at some point my coins will reappear. I’m case I export the keys please one more question. Do i copy and paste Bobs command into the console exactly as it is or are there part of the line I have to replace with my data?
Thanks again!

Hi I tried as you advised. This is not so clear to understand. If I put my original receiving address it opens up a page sayin on top balance at 0. Down in the tab of transactions I see 2 addresses one is of a transaction I did 2014 and the second address is pointing out the number that looks to be the balance after my transaction. If I click on this second one I enter a new page on top the balance is again 0. On the transaction tab I find 2 addresses again. One is the previous balance of the previous page and the second address is a second transaction I did in 2017. If I now click on the top one that again should be the remaining balance after the second transaction it opens a third page. This time the balance is not 0 but actually what I should have in my wallet.
Can you help one last time? Thanks

Thank you so much for your advice.
Sorry for my ignorance but how do I do that?
“If you’re really worried that your balance is gone, check the adress which previously(or still in this case probably) was used to store your funds in a blockexplorer.” I mean where and how do I find that address you are talking about?
 I’m tegarrs to the other point, I would have everything directed into an external storage which would still have one terra free. On my MacBook Pro I would have 5 gigs free (out of 500) but always get a notification that my storage is nearly full. 8gig ram. On the second computer I would have 16ram and it would open everything considerably faster.

Thanks again!

Dear all, I’m not a pro and need your urgent advice.
My computer was in repair after it came back I realized that there was a wallet backup on the desktop (I couldn’t prevent because my laptops screen was not working and the laptop needed a new motherboard).
All the rest of my data was stored on an external drive.
As the laptop came back I started bitcoin qt. everything was there, the correct balance and the past transactions.
It started syncing since it was at 73%, very slow but it would sync. 2 days later i shutter down bitcoin properly to facilitate a Skype call, since then when I start it wont connect to the peers. It would just stay trying.
Since my laptop is pretty full I took another MacBook Pro to see if that works to solve the issue.
I copied the whole bitcoin folder (with all the data) from the external drive to the new desktop. Though when I start bitcoin qt, there is an error message with the notification that the directory needs to be rebuild. When I do so, the wallet opens, I can see all the past transactions but the balance would be at 0. Also he would connect to peers properly and starts syncing from 0%. When I go back to the other MacBook Pro using the external drive, I still would see the correct balance but it still wouldn’t connect to peers.
I’m a bit worried, that my balance gone? What can I do for solution?
Thank you very much for any advice!
