ACR disables itself

Im using Automatic call recorder
it records all the incoming and outgoing calls on my phone
the thing is after a while, on a random bases, i find it disabled!
what happens is when i actually need to pull a record of a call , it didnt record it cause it was disabled, make the app completely useless
obviously i enable it back on , but somewhere down the line, in a day or a few hours it gets disabled again.
