General ⇒ problem running latex

[perrytom]

Thanks very much, that is the cause of the problem. However, I can't seem to update it - I've tried to reinstall it and even to uninstall it and then install it and nothing work. I've used MikTex package manager. Is there any other way I can do it?

I found the problem - it is generated when I use the latest update of the package biblatex, which is 1.7. When I use the older version (which is hard to come by!), which i 1.5, I get no problem. Do you have any idea what I should do about it?
