Very sorry! I did not manage to get the wallet working.
I thought I had a backup but that does not work either.
I will have to start saving all over again.
Fortunately, I have another 5 coins on Cryptsy
I know i did something stupid! Just bad luck!
what was your problem? What's the error-notification? How is loosing coins related to not get it to sync? I think it isn't. Delete blockchain and redownload with correct addnodes. Should be fine.
Does it take awhile to import the key?
yes, it rescans the chain. Can take several minutes.
I had a backup of my wallet.
Then everything removed. Then downloaded again. Updated blocks.
Only backup was gone. So the empty wallet now works fine.
