It took me some time copy/paste all the "adresses" carefully - but it worked!
Have you successfully created an [imported] Electrum wallet, not an [imported, watching-only] wallet?
Check the wallet's name in Electrum's title bar.
Or do you mean you've copy/paste all the "private keys"?
If yes, then it's all good.
I don't know the correct terminology and english isn't my native language, however - we learn it school as a side course for six years and then we have all american/english movies/series and ofcourse forums of a kinds.
However If yes? Yes! Keys
Again, thanks - your help was humbeling. <3
