Well I couldnt find a good way to get this working
But I did manage, I think to fix it
I ended up using mysql command line commands to insert a new row into the sys_user table with a new admin user.
then deleted out the admin user completely from the table.
So I can now login with this newly created admin user.
Not sure how well this will work, but should do for now, as I will most likely be reinstalling shortly anyway.
