I created MultiBit wallet in 04.2014, exported .key file for backup and kept using the wallet.
In 11.2014 I made a payment and MultiBit generated new address and sent rest of my bitcoin there. I wasn't aware of that and kept using my wallet thinking that my bitcoin is safe.
I upgraded to windows 10 in last august and with my .key file I was able to restore only access to my first address. Which was empty.
So that means there is no way to access the new address? Thanks!
When you upgrade to windows 10 the files are kept in specific folders. The files you need should still be there. ... or did you just buy a new computer and put the old one into the fire?
