[RWP] Urgent sollutions for stucking notes

[JR Live]

Hi guys. For those who are using QWS with Reaper, I really need your help. 
I need to finish a project tonight, but I keep getting stucked notes. 
What I mean is some notes are sustaining, and the only way to get it 
unstuck is to hit play and stop on reaper it self. It's killing me 
because it happens during playing the midi on QWS. Do you encounter this? 
any sollutions or tricks to get rid of it? Sorry guys. Hope you can help 
me...
