Hi, I lost my labels again! This time I didn't do anything out of place and I don't see any error messages.....
There still seems to be something wrong/corrupted with your electrum.dat file... Were you able to locate it?
It should be in the %appdata%\electrum directory, unless you're using the portable version. When you find it, try to delete it and restore the wallet from your seed. This should create a fresh electrum.dat file.
Hope this helps!
