How-to import Electrum keys

[38PTSWarrior]

I imported the single keys from the GUI in 0.9.3c. Then I re-scanned. How do I see in the balance history that it was correctly imported? Can I still import these keys in 2.0 or must this happen before? Thanks youu :)

I am a bit late with that. I remember that it did not work to import the wallet file. I then saved the keys somehow to a csv file which I have here.

I could get the wallet restored and the original wallet file but if you could help me with importing the single keys I would save some time (nerves).
