ShiMegaTen Devil survivor fps problem

I searched the forum before making this thread but couldn't find anything that address my problem. I started playing Shin Megami Tensei: Devil Survivor recently, on the latest version of no$zoomer with No$gba 2.6a and up until recently, it had been running fine.Today, and last night when I played though, the fps decreased to zero whenever I clicked anything on the menu, like when I restarted after making a mistake. I thought at first that it would be a matter of time but after waiting for about ten minutes nothing changed. And everything is fine till I touch the toolbar menu, which gets annoying if I have a misclick.Does anyone know how to fix this issue?

Did you change the no$gba or no$zoomer setting ? It might have some problem, since I never have that problem.
Try to change the setting or you may want redownload the program.
