Missing links/ text in process guide

Hey there

I got a problem with my Creo 3.0 student installation.

I can start Creo Simulate lite on my system and as far as I know, I have the licence for it, as written here:

But then I am in simulate lite, I can't do anything. But I don't even get a licence error.

I can't make my way through the process guide. The links, that you should click to define loads, constraints and so on are missing. The text boxes are empty.

According to a tutorial on youtube it should look like this:

What can I do about this?

Thanks and regards
