Did you try resyncing. I have sometimes had similar issues if my PC crashed. Deleting the blockchain and resyncing works for me.
Thanks Kazadar, i have tried that with no luck.
so far i have not been able to start the server since the upgrade

i keep trying every day in hope that it will just work but it never does. also tried reinstalling the entire thing and it keeps doing the same.
if anyone else has had similar issues please let me know the fix. i dont really want to wait till the next upgrade to start forging again
