the language is danish and iam danish guy, i hope guys, u can understand some of it

Hm, could you perhaps give us a translation of the main error message? My guess:

Det blev forsøgt at udføre en uautoriseret handling.
The blev(program? script?) tries to execute an unauthorized action.

Try updating it to the newest version

As a tech advice: If you can, try english versions. Translated ones usually have the most incompatibility issues.

The most possible is that maybe your DAoC Portal installation is corrupted. So uninstall it, restart pc and install the newest version as Metty says. Tell us when you fix it, so at future times people with the same problem have a fast solution. Cu.
