Hi, good day!

I'm sorry to hear that you have experienced this. This might be an issue caused by the device itself.

You can try the following suggestions:

1. Restart your device, then check if it works already.

2. If not yet, you may reinstall the software. Verify that you have the correct bit version for your system (64 bit or 32 bit). Then restart your device again.

Alternatively, you may access PI Expert Online through your web browser. It is fully integrated and no installation required. This way, you will also receive updates and new features as they are added. 

Let me know if you have any more questions. Thank you.
