Anybody use Drop-x by Beatskillz ?

Got this plugin in my project. Used it for a certain part, all fine. Used another instance of it in same project. Now the trouble starts. It will play what I program it to. Then it stops working. It won't output the sound, it won't record sound into wav loop or final export version. Plus the step bar locks on whatever it was assigned to. The first instance I used drop-x on still works. Now I tried reloading the plugin...setup my sound again & then it won't output the sound all over again. Reloaded FL studio 12, start new project... played around with drop-x & it's still causing the same problem in a new empty project. it's driving me nuts, was finally get somewhere with my track until now. Was thinking of reinstalling the plugin, but worried I might lose some project progress which I used drop-x on in my first instance (tinkering for ages). Does anyone have experience with drop-x that could help ?
