I have sent an email to the ninjas a couple of days ago and got a reply today. The problem isn't solved yet, but we're in touch. :-)

I have unsuccessfully re-installed OF already before I started this thread. (More precisely: I replaced the "Version 1.7.3" with the "English-only Version 1.7.3".)

One thing I'm going to try is to create a new user account and install OF there. But I can't do this before monday because I have these troubles at my workplace and I am at home now.

Again, thanks for all the answers.
