Old JSON wallet



The last time I tried to Sync my desktop wallet it got stuck ( A year ago ).
Now all I have is an old JSON wallet and some old keys that were emailed to me.
Am I screwed? Or is there still a way to import my wallet.
I have something like 3300 smart.

When I try to import my private key from the email in the web wallet.
I get this error message:
Error: The version prefix does not match the expected one 191



You can install the latest wallet version and import your wallet.dat backup file
