'no documentation available' in Creator linux x64

Hello,
When I press F1 when the cursor is on some class or method I get 'no documentation available'.
I installed creator in kubuntu 10.04 with 'sudo apt-get install qt-creator'.
Previously I download creator from the site and installed with it's own installer, I had the same problem but I could add the creator.qch manually and that would fix the issue.
That solution doesn't work anymore though..

Thanks.

Never mind, I downloaded the webversion again, and now all is fine. Sorry.
