LB Booster does not work in Parallels/Windows 11

I have set up Parallels on my Macbook Air M3 with Windows 11 Pro VM.
It runs just about everything that I throw at it, with the exception of LB Booster. This is a tool based on Liberty basic 4.5.1 which runs most Liberty Basic Programs. It works by converting the code from Liberty basic to BBC Basic for Windows and then runs the converted code. Both Liberty Basic 4.5.1 and BBC Basic for Windows run fine, but LB Booster loads up its IDE but then on running the code comes up with and error "Syntax Error at Line 1" no matter what code is run.
Is anybody able to shed any light on the problem and solution, or have I to just write it off for use under Parallels.
