Have you used the script to update the permissions? If not please try this:
Within the SQL script dialog window of your database management tool, run the following script.
GRANT Create View
ON [db name]
TO [db username]
Replace [db name] with your Powerstore 3 database name.
Replace [db username] with your database user account.
Let us know if you get any errors when you run this, afterwards you should be able to create views.
