What surprised me is this part :

__Method 'AddWebException' in type 'Tweetinvi.Logic.Exceptions.
ExceptionHandler' from assembly 'Tweetinvi.Logic, Version=0.9.7.1, Culture=neutr
al, PublicKeyToken=7247f14397bf67b9' does not have an implementation.__

Can you please tell me what could be the problem?

Thanks in advance
