Something is odd on your two posts.
they each show a different database name.
Your first post it is:
thorsten_ubb.w3t_Users
Your second post is:
thorsten_dattabase.ubbthreads_Users
Are you trying to use a existing database with data in it?
If so you would not run the install script?
As far as a download goes you would need to pay for member access.
ubb6 is there but it is a discontinued product.
But by paying for member access with your current license you would have access to the current version 7.5.6. as well.
