error message(s) or blank window MySQLi query builder

As soon as I click the button 'query builder' in the advanced tab from the Webassist MySQLi extension, I get an error message, i.e:
Error Inspecting SQL
• table not found: portfolio_i
These values will be automatically removed the next time

or a blank window or DW2014.1 stops running.

Earlier on everything worked fine (used it in another website), but now I get only frustrated.
I removed and reinstalled the extension, nothing changed.

A new mysqli recordset in simple mode is a piece of cake, but I have to inner join some tables in advanced mode with the query builder.

Does that column exist in your database? Does it show in the tables list in the Advanced window? What is the SQL statement you are starting with?

Can I get FTP access and a copy of the page to reproduce?

Yes, the table and column exist.
And they all show in the tables list in the Advanced window.
I am starting with a SELECT statement of all table columns in Simple mode and then click the Advanded button.

This is an issue with the querybuilder not working properly with reserved words and special characters in column names... In this case the dash in your table name was causing the issue.

I've made an update that should address the issue, so please try uninstalling and reinstalling the extension and I think it will work properly now even with dashes in the table names.

Thank you for the feedback and update, but it still doesn't work with the dashes in the table names.

So I renamed all my tables (dashes to underscores) and adjusted the concerning code in my page. And guess what: the query builder works! Sometimes DW shuts down opening or closing (clicking the OK button) the query builder, and sometimes it works faster coding by hand, but my problem is solved for now.
