Thank you doing this solved the problem i was having
In that case, it sounds as though you may have some corrupted files in the default Electrum "data directory". On windows this is usually in %appdata%/Electrum. (should be something like: C:\Users\YOURUSERNAME\AppData\Roaming\Electrum)
If you have your seed safely backed up (and/or wallet file if you have a non HD wallet)... you should delete everything in the %appdata%/Electrum directory, re-install the latest Electrum and then restore your wallet.
