Hi every one! I've recently finished open univercity course on osemosys and flextool. after finishing flextool part i've starned again osemosys modeling, but i always got this error, even while running Hands on, that has already been ran succesfully.
What am I doing wromg? Even the easiest models, only with backstop technology cant be modelled with clicSAND, but momani is still working.
