Yesterday I had this error message when my PC was booting up (the Zen broadband usage checker loads automatically)

Earlier on this afternoon I got this error:

In both cases I was able to log into the Zen Customer Portal and closing down the broadband checker by selecting the 'Exit' option and reloading it solved the problem and it worked again.
Anyone else get this?
p.s. I'm using the Windows version 2.0.6.0
