Windows 7: Error 557 + Audio Label software

Hi...I'm running Windows 7 Home Premium (64-bit)
I recently installed Audio Label software, a CD/DVD label maker, jewel case inserts etc

It installed without any problem but whenever I start up Audio Label, I get a small window popping up showing: 'Error 557' with an OK button.
When I click on OK, the window disappears, Audio Label opens and can be used fully.



However, I'm finding it niggling to have that Error 557 everytime and I believe it's because of a missing 'dll' file, but which exactly?

Why on earth give such info if you don't show a person how to 'fix' it or at least direct him in some way? OK is NOT OK!
I've uninstalled and re-installed Audio Label to see if that cured the problem...but same result.

Can someone help me fix this?
Many thanks
