Downloading the torrent file works. Thanks for the advice! And btw, the support on this forum is great.
I don't get it, though. I've downloaded tons of programs, never bothering with clearing the cache, checking the md5-sum or stuff like that and I never encountered any integrity errors. I've tried installing ooo on several computers (in the different ways that are advised on this forum) and it comes up with this error consistently. How come?
