Easydiscuss update to 4.0.5 --> receiving an 1054 error

Dear stackideas,

We have an issue here. We where running on easydiscuss version 3.92x back then the extension worked great but since we run the update to version 4.0.5 we received an mysql error --> error 1054.
In the installation proces everything seems to be alright and no given error but when we completed it and check the website we received this error. Only on easydiscuss by the way. We are also running easyblog, easysocial and Komento on this website and those extensions all work fine.
(See my attachments for the installation proces and the error)

Can you please look into this?

I like to hear from you soon.

Kind regards,
