Please provide the necessary information, such as your:
- Operating system and version and
- Wallet version
Further, did you try to update electrum?
If you have your mnemonic code (the 12 words), you are fine and can always recover your funds.
You might want to copy/backup your wallet file and upgrade electrum to the latest version. Then check whether there are still some issues.
If it is the most up-to-date version, open electrum via the command line and tell us any error message you encounter.
