WM recorder can't record after upgrade to wmr12

[Linyx]

I have been using WM Recorder 11.3 recording mms link in pro mode because the stream consist of multiple video and recording it in ada mode will record only the introduction video.

I downloaded the trial version for wmr12 and unsuccesfuly record the video. There are no error message, just that wmr12 is not responding everytime I played the mms link.

I revert to 11.3 and I cannot record anymore, no error message

Please, I need some advise

Thank you
