I've mined a lot to this address. Is there any way to recover?
EDIT:
I solved this by copying the default_wallet file from the old wallet to the new one. I was using Win 7 with the version that wasn't working, Switched to Win 8.1 and it works fine.
I'm new to Electrum. Does this mean that the only way to restore an electrum wallet by seed or key is by having a backup copy of the wallet file?
EDIT #2
It looks like I can't mine to the Electrum wallet. What else would I use it for? lol
I still use the old Electrum wallet and works fine but need to upgrade.
My wallet is on mac does mac also have a default_wallet file somewhere? Where can i find it?
The default wallet file is called default_wallet, which is created when you first run the application and is located in the /wallets folder.
On Windows:
Show hidden files
Go to \Users\YourUserName\AppData\Roaming\Electrum\wallets (or %APPDATA%\Electrum\wallets)
On Mac:
Open Finder
Go to folder (shift+cmd+G) and type ~/.electrum
On Linux:
Home Folder
Go -> Location and type ~/.electrum
