I'm using the latest version of Ace (version 1.3).
I've just downloaded the lastest version of FuBar (1.1.1580) and tried ckknight's suggestion of loading it on it's own. Guess what?! It's working - so it must be one of the plugins.
Now I'm gonna start loading the latest versions of each plugin I have one by one until I get the error I was getting. If I'm lucky I won't get any! I'll post a reply telling you which plugin is giving the problem.
Thanks for your help guys
