For PARADISe v6.1.6 (or earlier), when the license expires (trial or yearly) the program fails to open and give an error message. The error is:
"
Access is denied
Error in => mainFuncForNumericStandaloneApplication.m at line 13.
"
This is an unintended behavior, as PARADISe Professional Edition should fall back to PARADISe Community Edition. This has been fixed for the upcoming version of PARADISe.
For PARADISe v6.1.6 (or earlier), you have to manually delete the license file located at "$USER/Documents/PARADISe/license-paradise-professional.mat" then PARADISe will start up in the Community Edition.
