Streamserve error "Fatal error: License not present: preformatin" using -demo argument

FRAZO

Hello community, recently I tried to use preformatin input connector in StreamServe 5.6.2 version, I used the -demo argument in the Configure Export section to try to run my project in demo version which does not require any license, however no matter what I try, I it always throws the error Fatal error: License not present: preformatin:

I'm not sure why this error continues to appear even using the -demo argument, so any comments would be highly appreciated, if you have any questions let me know, thanks in advance for reading!
