Update Wordbooker 2.1.32 error (wordbooker.tmp)

Hi. Today is received a notification for an update for Wordbooker. I was pleased because since the last update Wordbooker gave me trouble whenever I wanted to publish a post; it got stuck after i clicked the publish-button. It did publish though but the adminpage froze.

So, today, after receiving the 2.1.32 update and hit ‘update’ I got this error (Dutch):

“Map kan niet aangemaakt worden. (..)eamel.net/public_html/blog/wp-content/upgrade/wordbooker.tmp”

Other updates gave no errors; just Wordbooker. I uninstalled it and tried to install it again with the same error as a result.

In short; what is the problem? There nothing wrong with the CMOD. Help anyone?

(Excuse for my poor English; it has been a while ;-))
