Hi ST I have it on mine and it went though ok, When you click the activate Icon you should uncheck the add a bookmark for givaway of the day unless you want to bookmark it, then let the webpage it opens after you click ok should work. If not follow this as it says if you have problems.

If you have a problem with registration, do following:
1. Download http://www.sytexis.com/bin/cfgeditor.exe
2. Run it - it will open configuration folder. Delete config.txt file
3. Run PlayClaw again.
But it worked ok for me without having to do it.
