Hello
I am having the same problem as the OP, but I don't quite get the "sweeping" solution? Can somebody please explain that to a non-techie? Sorry for being stupid
Your help is much appreciated!
Click "wallet" in the top menu bar, then move your cursor down to the "private keys" entry in the dropdown list that opens, then move it to the "sweep" entry in the second dropdown list that opens, then click your mouse.
Afterwards this window should open.
Enter a list of all the private keys you want to sweep into the window, then click the "sweep" button.
