Hey!

I'm do not know any Java-programming and have tried "Googeling" the answer without any success.

I'm trying to run a jnlp-file and it says that "the certificate could not be validated" and that due to security reasons the applikation has blocked it from running.

One of the things I've tried is to lower the security-level and just "checked" all the options that says something with "allow" :)

Here is a link to fhe files:
Nätkurs (http://webcourses.itn.liu.se/)

I haven't tried all of them but since they come from the same source I guess none of them works.
But to be shure, click on the first picture that says "Visualisering av rotation " a bit down to the left.

My operating-system is windows 7 and I'm using the latest version of Java.

Would really appreciate any help on this! Thanks
