If you have any problem installing, using, updating or downloading my software, please don't hesitate to contact me.
If you've donated or bought a package, please email me using the PayPal email and including the Transaction ID (this will grant you the support for the product, otherwise I'll reject the email). Free software (with no donation option) will allways receive support.
You can even see the FAQ page of the WoW Progress Tracker where the most common errors are pointed out.
To keep you informed, you can subscribe to my newsletter (see every project's page), follow me on twitter or simply visiting the site periodically.
