Oeps, it seems like the default maximal cost given in the GUI is 0??? 
This might be the problem. I ame rerunning the line below without the 
max_cost=0 (stupid me...). Hope this will solve the problem.... it is 
now running for 4 minutes, so I let you know if it is actually solved 
somewhere later today, tomorrow...?
