So, Ive inserted ALL the keys in Electrum but the "Next-button" isn't highlighted. Only back.
There are two icons, QR-code and read file.
It should work, hope it is the real private key that you imported? You can use this guild for the private key importation
Importing your private keys into ElectrumAlso, if you are importing multiple private keys, use below format:

5KS1wBgCUhvW6Cr2kxu1dgnszHfNzGdfKzCaVDndaFLWbvKzQYU
They are all private keys.
All started with a 5.
I've checked for any spaces and stuff like that. I must have made an error somewhere, have to do it again - there are ALOT of keys...
