There are problems with urea synthesis

Now, for some reason, my Aspen keeps showing a dialog box whenever I try to open files, run simulations, or save files. The dialog reads: “The following engines are missing: usrpp1a.dat, usrpp2a.dat, usrpp1b.dat, usrpp2b.dat. Do you want to continue?” This problem persists even after reinstalling the software; I’m not sure what’s causing it. Additionally, when using the PFR reactor model and trying to view the stream results, the program crashes. I hope someone experienced in this area can help me figure out what’s going on
