Text and Object stuck on camera without scanning target image

Hello,

I am a noob when it comes to using Unity and Vuforia. I have been following the guides on how to set up a simple augmented reality app and have run into an issue. After following all the correct steps such as deleting the main camera, importing the AR camera, creating a database on Vuforia, importing this database, activating this database, activating the image target with the database, making the image target a child of AR camera, placing a 3d cube as well as 3d text as a child of the image target and AR camera i have run into an issue. For some reason when i hit play the camera version shows whatever object in this case the cube and 3d text on the camera screen permanently without scanning the target image. The objects are just stuck on the screen permanently. I'm not sure what might be causing this. When i select the AR camera there is a message that says "No webcam profile has been found for your model: 'Lenovo easy camera'. I'm not sure where to go from here but any help would be greatly appreciated. 

Thanks
