Getting error while importing Axmodel in DMF beta 2.0

Hi All, 

I have installed Intgration services, AOS Instance, Client in the server machine. Now I'm trying to import ax model but I;m getting this error "The pipe line has been stopped"

I'm writing this in powershell in the below format

axutil import /file: "C:\Program Files\Microsoft Dynamics AX 2012 Data Migration Framework Client Components(Beta)\DataMigrationFramework.axmodel" - Conflict Push
