drivers - USB Stick is recognized by PC but cannot be opened

My new USB Stick with important data can't be opened by my or my friend's Windows Computer anymore. I can tell that it is recognized by it since a "device" is "mounted" under E:/ and my computer makes a sound when I connect it but it won't show the USB's original name nor does it allow me to access the data.

When I click on it it asks me to insert a USB-Drive.

1. I have tried already to deactivate and reactivate the USB Stick


2. to deinstall and reinstall drivers for the USB-Stick


3. to rename the driver letter from E:/ to P:/ and back to E:/



4. and put it into the freezer for 20 minutes (my friend recommended this)

I hope anybody can help me out with this as the data is really important to me.

Here is the data that my system gives me for the Stick:

Edit 25.12.2016 - Opposed to another question posted here I have no access to the storage size information of my flash drive - hence it must be a different problem.
