problem with response box

[baruche]

ok. we connected the problematic bit (248) to a potentially free bit (112) BUT after the instructions screen,that is on the presentation of the first -- to be respoded to stimuli -- we get a very strange message:
"NTport library v2.4 cant find valid registration information. please call license info function with the registration key befroe call any other function of NTport library. refer to the doc & samp for details"
any ideas?
attached to modifed version of the input file.
thanx
