Mwan stoped working after sometime when using it on idm

anyone help me please, how to fix MultiWan stopped working after sometime in download manager. how to make it working consistent untill the download finished?

I think it can be, because after I press pause on download manager and start it again MultiWan can works normally but after sometime it back to 1 interface only working

But is there another way to make MultiWan work consistently so I don't have to repeat pressing pause and start for on download manager?
