Cannot access the WebDesigner, need to change standard error message

Hi,

I´m a student who is currently evaluating K2 Blackpoint. I´m trying get it to work at the moment.

But there is a big problem: Every time I click on the WebDesigner I get an standard error message. I tried to change that by changing this in the web.config files I found, but it didn´t work.

I already did some reasearch and found this thread:

Sadly I don´t really understand what to do with the IIS. I tried to find the web.config with it, but couldn´t.

Now I´m at a loss because I can´t change the error message and without it, I can´t try to find a solution for the original problem.

Any help on this would be GREATLY appreciated.

bye,

Matthias
