Maybe your files were overwritten by other data. In this case there is no way to retrieve the data. However, it will be better if you can tell me some detailed information: The model of your Android, the Android OS version and the system OS so that I can have a better understanding of your case.
As for your case, please do as following steps to fix it:
1. Please make sure you download the latest version of the program.
2. Please keep your device powered on and USB debugging enabled
3. Re-plug your USB cable to connect the device.
4. Make sure the right driver installed in your computer. Here is a link to find the right driver of your device:

Could you please tell me more detail about your Android device like phone model, Android OS, Windows OS and give me the screenshot of the interface. And we will work out this.
It is possible that your Android is overwritten and if our program can't find your data, I am sorry that nothing we can help because once the file is overwritten, the previous data are deleted and can never come back. By the way, remember to back up your the data frequently so as to lessen the loss that losing data cause.
May I have your phone brand, device model and Android OS please? We will work on it with the detailed information of your case as soon as possible.
Sorry that Myjad Android Recovery only support Windows system, included Windows 8, Windows 7, Vista, XP (64&32 bits). If we release a Mac version, please learn more from our official product page. Thanks for your patience.
