Cuecat gives off error but no code

Hi I am running vista on a laptop and have bought a cuecat.

My problem is that even though I've followed the advice in
http://www.librarything.com/talktopic.php?newpost=1&topic=3366#lastmsg
and make sure the cuecat shines red before scanning I get no result.

Most of the time in either notepad or library thing I don't even get a code at all, then one try in 50 I get this as a result " 5YBN6....................."

I've tried fast and slow, hold the cue cat differently and scanning inside covers, but no result.

Any help would be appreciated

I've just replied to your other post. Oh and the image you linked to is too small for my old eyes:
