Thanks for the quick response.
This is probably the reason for the issue, wheezy is a rather old version of Raspbian.
We already went through Jessie lite and to the newest version Stretch during the last few years.
First, you can try making an apt-get upgrade in the Raspberry Settings to update your packages.
But if that does not solve the issue, please consider burning our newest image based on Raspbian Stretch.
You can download it free from this website and follow the wiki on how to burn it.
