Same circuit from Web to Desktop not working

Hello I found circuit on multisim.com that I need for 10-25V to 5v.. It works great on web version (ie very slowly), at 10V, it stays at 5V output..  I copy the circuit to MultiSim desktop but at 10V its only 3.2V, also i have an AC rectified source which I try to replace the DC input, but multisim desktop won't work with them connected, it says error running simulation.. Both work independently (except for the 3.2V thing)

Borrowed schematic

I have attached the ms14 file and image of circuits I try to combine.. I try to get 5V fixed output from 8-31V AC input
