Hi Gordon, thanx from rainy Germany for your fast answer. I tried the trick with putting the source file (you mean the html version?) of the Hotpot Exercise into the main file directory and then created a hotpot activity by using the link , but this did not work, I got:
Could not open the XML source file "inside_a_hard_disk.htm"
Do I have to be a "normal" admin or a "primary" admin to do this?
Anyway, I will continue now in the old method, waiting for one of you terrific guys to find a solution one day. Thanx again!
