Portmaster PC Ports not working on my device?

I’ve got my Portmaster and MuOS up to date yet my .sh files are not working on Portmaster. Ready to run games are working just fine but games like GTA III & VC via Portmaster aren’t starting. I’ve tried reinstalling the games but it didn’t seem to make a difference

Did I drop my files in the wrong place? ROMS > PORTS > .sh files
