Unable to update my email address

[Sven]

I can't update my email address in the profile since it keeps on telling me that I didn't fill it in.

I'm sure I did so there must be something wrong....

What's the exact error message you are getting?

[Sven]

It was something like "you didn't fill in the required email filed" (or so) but never mind, it worked now ;)
