Heart Buddy does not work! Please help

Hello everyone,
recently i purchased Hearthbuddy. But unfortunetly it didn't worked as expected. After some research i found several post in this forum which had several solution but
nothing worked for me. First of all, the problem is when I start Hearthbuddy it crashes. After looking into the Logfiles I found the following message.

Error inside the Logfile :
2015-04-10 21:30:18,910 [1] ERROR Logger (null) - [Application_DispatcherUnhandledException] Unhandled exception
System.IO.FileNotFoundException: Could not load file or assembly 'GreyMagic.dll' or one of its dependencies. Das angegebene Modul wurde nicht gefunden.
File name: 'GreyMagic.dll'

at MS.Internal.Threading.ExceptionFilterHelper.TryCatchWhen(Object source, Delegate method, Object args, Int32 numArgs, Delegate catchHandler)

After quick search i found that I can use the BuddyWizard to install all dependencies. So I downloaded the tool. After the first start it also crashes,
while checking if all is there(.Net Framework and stuff). Ok, then i uninstalled all patches including the .Net Framework itself. Installed an older version again,
still the same problem. At the moment i have no idea what's the problem there. Can you provide me help ?

Greetings,
Mike
