The way that the software works depends on the yellow page website which holds all the data. The software has implemented parsing logic so that it can grab the contact list from the website. If website changes its page content in such a way that the parsing logic doesn't work anymore, the software won't work with that website. This is why you are seeing this issue.
To solve the problem we release the new version which has the new parsing logic to work with the website. Please see
how do I install the latest version. Your software purchase comes with one year free upgrade. After one year you will need to purchase the
upgrade version to have another year of upgrade.
