Hi, i’m having some trouble i hope someone can help me, whenever i try to use the Whawha efect from nasca octavian paul a window apears saying Audacity “ha dejado de funcionar” wich means it has stoped working, someone knows something about this? thanks 
Ps: sorry for the ban english i’m from argentina 
Does the problem occur with just one Audacity project?
Does the problem occur with any other effects?
Can you give step by step instructions for how we can reproduce the problem.
Which version of Audacity are you using? (Look in the “Help menu > About Audacity”)
Which version of Windows are you using?
Sorry for not answering sooner, i had lots of exams, i have the 2.0.2 version and windows 7, the thing is actually quite strange cuz when i try to use the efect, i select a part of the audio and select the wah wah effect and if i press preview (vista previa in spanish) it sounds fine, nothing wrong, but if a press aply (aceptar i think it says in spanish) the program crashes an closes itself and sends me back to my desktop, i hope this is enough info but if you need more tell me and ill check, thanks a lot for taking the time to respond, and again, sorry for the bad english
Please try this:
Starting from Audacity being closed (not running):
What happens?
Audacity stoped working, windows is searching for a solution, then it closes, that’s it
Do all of the other built-in effects work?
