Pingendo on Mint 17.3

Hi guys. This is my first foray into AppImages and Pingendo. After setting the downloaded file to executable and running it I get a window that opens with nothing in it except whatever else was under it before it was there. When I run fro the command line I get the following:

aunty@vanessa:~/downloads > ./Pingendo-4.2.1-x86_64.AppImage
/tmp/.mount_PingenpgatDK/Pingendo: /lib/x86_64-linux-gnu/libdbus-1.so.3: no version information available (required by /tmp/.mount_PingenpgatDK/Pingendo)
/tmp/.mount_PingenpgatDK/Pingendo: /lib/x86_64-linux-gnu/libdbus-1.so.3: no version information available (required by /tmp/.mount_PingenpgatDK/Pingendo)
[16:50:59.449] [info] Checking for update
checking for update…
[16:51:07.517] [info] Update for version 4.2.1 is not available (latest version: 4.2.1, downgrade is disallowed).

I tried the dive log program on the AppImage main page and that seemed to work.

Any help will be appreciated. Cheers,
Aunty
