Thanks yes it is a clean electrum and I have the seed safe
The best way to verify if it's clean is to verify the file, did you do it? (tutorial:

Also, Importing it to another wallet means it'd be available on both ends (previous & present) so it's recommended to generate a new seed and send all the funds there.
the balance is there but I try send out of electrum and I get this - 'The server returned an error when broadcasting the transaction. Consider trying to connect to a different server, or updating Electrum. Unknown error '
Have you solved this? here's how you change the server
