user71514: Have a multibit.key file from an old Multibit Wallet, but can't import it into Electrum. 
When I copy and paste the char string from the file into the "Import Addresses and Private Keys" Electrum window it just never allows me to push Next and proceed. 
What am I doing wrong? Is there any other way? 

user48461: Got the same problem, and the only solution I found was to send all my bitcoin to another address (remember to put the fee to the maximum amount) because it was also impossible to import this key on the the new Multibit HD wallet...
You're not doing anything wrong except trusting multibit back in the days to store your bitcoin...
