Formbuilder problems

Hello,

I've been trying to put a form on my site, but I've hit a roadblock and I'm very stuck. I installed Formbuilder from Truth Media, but underneath the text box of my pages I see a little bar that says this:

Error: Unable to load field details from table. [SHOW FIELDS FROM `wp_formbuilder_forms`]

I posted on this last month and people who responded told me that I should have gotten a drop down menu. I think I'm getting that error message instead. I have deleted and then reinstalled formbuilder and it doesn't make a difference (tho when I tried to uninstall following their instructions, it also did not work). I've uploaded from my desktop instead of downloading straight from the site and it still made no difference.

I contacted the formbuilder folks, but still haven't heard back from them.

Sorry to post on the same topic twice, but I'm really frustrated. Does anyone know what might be going on and how I could fix it?

Thanks for any help!
