That's kinda strange. If you have a basic account (e.g. just for the forums), then there's no need for the browser to take you to or load anything from the Klambach website. It sounds like there may be a problem with the DNS entry on your computer. In which case, go to the command prompt (Start -> Accessories -> Command Prompt). Then enter ipconfig /flushdns
This will cause your browser to re-resolve DNS data instead of relying on old information (most websites automatically update this for you....some fall short).
Apart from that, you could try clearing the cache/cookies. This shouldn't be the cause, but I suppose it's worth a try. Depending on what browser you're using, you may need to check Google for where the cookies are stored (usually in a hidden AppData folder in your personal [username] folder). Or you could download a free program like CCleaner to clean out unnecessary files like cookies. It's pretty safe, and I use it all the time.
Hope something works for you.
