zANTI not working on my Samsung galaxy TAB

So i just downloaded zANTI for my samsung tab to see if it works and to my surprise it didn't :(
When ever I try to do a MITM attack i get this error

Error setting http interception

nc: bind: Address already in use

java.lang.Exception: nc: bind: Address already in use
at com.zimperium.zanti.ZHttpInjector.n.run(ZHttpInjec torService.java:130)

If you could help me it would be great!!!! :D
P.s. Admins if this is in the wrong topic please move it for me since i am new to this
