Do you have to send Ardor from your "address" to another "address"? In this case, try to access the link I have already given you. You can do it from there without having a hardware wallet.
If your problem is the hardware wallet? Save your login details.
I would do like this:
Ardor installer may be corrupted, try downloading it again.
Uninstall your wallet, delete every file, reinstall it.
ardor.jelurida.com is a read-only wallet, you won't be able to submit any transaction from there.
To operate on the mainnet it's recommended to use your own node. If you node doesn't update make sure you are using the latest version downloaded from jelurida.com. You can start from an empty database (deleting the db_prod directory) or download a current database from the website (Ardor Downloads | Jelurida).
If you still have problems after following these steps please share your log file from the server.
