"Object reference not set to an instance of an object"

Hey all,

It seems my HB is having trouble attaching itself to WoW. I have tried a number of techniques (with the help of Tony) to fix the problem including:
-WoW repair
-Re-downloading HB client /restarts etc
-New admin. account
-Disabling firewall/AVG/proxy

However, the problem still persists. The current log file is:

The latest log is as follows: [8:38:10 PM:857] -------------------------------
[8:38:10 PM:859] You have not selected a valid instance of WoW to attach to!
[8:38:10 PM:859] Please restart Honorbuddy and choose a valid WoW instance to use Honorbuddy.

I am using Windows 7. If anyone can help out, it would be much appreciated. Cheers.
