iTunes refuses to load

Every time I go to start iTunes I get an unknown error (13026). I have tried uninstalling, reinstalling, even taking the iTunes folder from my old hard drive and overwriting it on this hard drive with it and yet it still refuses to load. Any idea's on fixing this would be appreciated.

I already looked at that and tried it, it didnt work. Thats why I'm looking for help here.

 

I'm having the same trouble and am tempted to perform a system restore to try to solve things. Any other suggestions? Very frustrating - wasted a couple hours trying to uninstall, etc.
